7 Honors Physics - First Semester Exam Review Answer Section PROBLEM s seconds cm m m s s m/s 30 v(m/s) t (s) a) 0.80 m/s b) 0 m/s c) 1 m/s d) 1.6 m/s 13. In the first case, the glass is experiencing free fall from a height of 8.00 m.

8 t = 1.81 s In the second case, the glass travels upward at an initial velocity of 1.5 m/s, stops, and returns to the height of the balcony before experiencing the free fall of the first case. Since we are concerned with events after the glass is thrown, only the positive time is correct. 14. The child is just barely successful. = v i + at f 0 = 0 m/s + (-9.8 m/s )(t) t =.0 s d f = d i + v it f + 1/at f d f = m/s (.0 s ) + 1/(-9.8 m/s )(.0 s) d f = 0. m 15. The ball both begins and ends with zero displacement. d f = d i + v it f + 1/at f 0 m = m/s (t) + 1/( 9.8 m/s )(t) 5 m/s = 4.9 m/s t t = 5.1 s 16. d f = d i + v it f + 1/at f 760 m = 4000 m + 0 m/s (t ) + 1/( 9.80 m/s )(t) 340 m = 1/( 9.80 m/s )(t) t = 6 s 17. The gazelle s velocity is constant, so the acceleration is zero. 18. The acceleration of the cheetah is 180 m/min / 3 s = m/s / 3 s = 10.1 m/s. 19. d f = d i + v it f + 1/at f 1 m = 0 m + v i(0.75 s) + 1/(9.8 m/s )(0.75) = v i(0.75 s)

9 .34 m/s = v i 0. The displacement for object A after 5 minutes is 5 m/min 5 min = 5 m (north) The displacement for object B after 5 minutes is 3 m/min 5 min = 15 m (south) The difference is (north). 1. Line E represents two separate events: Walking north with decreasing acceleration for 5 minutes, coming to a complete stop for an instant, and then walking south with increasing acceleration for 7 minutes. The displacement for part 1 is: 1/ bh = 1/ (5)(4) = 10 m north. The displacement for part is 1/ bh = 1/ (7)(5) = 17.5 m south. Thus, the overall displacement was. The displacement is equal to the area under the curve. In this case, we have a triangle. The area of a triangle = 1/ bh. Displacement = 1/ (5)(5) = 1.5 m to the south. (The displacement is to the south because the velocity is negative for the entire duration of motion represented.) 3. The displacement is the area under the velocity-time curve. In this case, the area is a triangle with a base of 6 and a height of 6. Area of a triangle = 1/ bh. Displacement = 1/ (6)(6) = 18 m to the north N m/s to left N N N N = 460 N N N = 170 N toward the smaller force. 30. The mass of the second sled = 4 times the mass of the first sled g s indicates that the force on the pilot is 5 times the force of gravity. Thus, her apparent weight would be 5 times what it is on the ground: lbs. = 650 lbs. 3. The normal force is equal and opposite to the force of the orange crate resting on the apple crate. The force of the orange crate on the apple crate is the mass of the orange crate plus the mass of the strawberry crate, multiplied by g. Normal force (apple crate on orange crate) = (0.0 kg kg) 9.8 m/s = 94 N 33. The normal force is equal and opposite to the force of the strawberry crate resting on the other crates. The force of the strawberry crate on the orange crate is the mass of the strawberry crate, multiplied by g. Normal force (orange crate on strawberry crate) = (10.0 kg) 9.8 m/s = 98 N 34. The normal force is equal and opposite to the force of all of the crates resting on the loading dock. The force of the crates is the mass of the apple crate plus the mass of the orange crate plus the mass of the strawberry crate, multiplied by g. Normal force (loading doc on apple crate) = (5.0 kg kg kg) 9.8 m/s = 539 N 35. F net, 1 = M 1 g T = M a F net, = T M g = M a The accelerations are the same because the blocks are connected by a taut string.

10 (M 1 + M )a = (M 1 g T) + (T M g) a = g a = 9.80 m/s a = 9.80 m/s a = 1.78 m/s M 1 is moving downward and M is moving upward. 36. a = F/m a = 170 N / 300 kg a = 0.57 m/s Recall that = v i + a(d f -d i) = 0 + (0.57 m/s )(5 m - 0) = 8.5 m /s = 5.3 m/s 37. a = F/m a = 0.5 N / kg a = m/s Recall that = v i + a(d f -d i) = 0 + (78.15 m/s )(0.75 m - 0) = 117. m /s = 10.8 m/s 38. a = F/m a = 50 N / 6.8 kg a = 7.35 m/s Recall that = v i + a(d f -d i) (15 m/s) = v i + (7.35 m/s )(8.5 m - 0) 5 m /s = v i m /s = v i 10 m/s = v i 39. Recall that = v i + at a = ( -v i )/ t a = (50 km/h 90 km/h) / 15 s a = ( 40 km/h) / 15 s a = ( m/s) /15 s a = m/s F = ma F = 450 kg ( m/s ) = 330 N 40. Recall that = v i + at a = ( -v i )/ t

11 a = (70 km/h 40 km/h) / 8 s a = (30 km/h) / 8 s a = (8.33 m/s) /8 s a = m/s F = ma F = 50 kg (1.041 m/s ) = 60 N
