1 Vive Le Quiz de Physique! FOR FULL CREDIT SHOW ALL WORK SIG FIGS COUNT USE THE FORMULAS BOX THAT ANSWER 1. Kedge straps a jet-pack to a red wagon. He gets in the wagon, ignites the engine and, from rest, accelerates west to a velocity of 389 m/s in 9.34 seconds, what is its average acceleration? What is the displacement of Kedge and the red wagon during this time? 2. If a car is moving at 3.2 m/s, how long will it take it to reach a speed of 22.0 m/s if it has a average acceleration of 2.5 m/s 2? 3. A rocket traveling east, reaches a speed of m/s in 8.00 seconds after an average acceleration of m/s 2 occurs. What was the original velocity of the rocket?
2 4. True (T) or False (F) : Motion is speed in a given direction. Speed is the change in position of an object in a certain amount of time. The velocity of a car can be described as 60 km/h to the North. A scalar quantity has both magnitude and direction. Displacement is a vector quantity. An object cannot be moving if its acceleration is zero
3 Viva La Prueba de Física! FOR FULL CREDIT SHOW ALL WORK SIG FIGS COUNT USE THE FORMULAS BOX THAT ANSWER 1. True (T) or False (F) : Speed is a scalar quantity. If speed is constant, acceleration must be zero. The velocity of a car can be described as 60 km/h to the North. Speed is velocity in a given direction. Velocity is a vector quantity. Acceleration is a change in speed or direction 2. A car traveling south, reaches a speed of 27.0 m/s in 7.00 seconds after an average acceleration of 3.25 m/s 2 occurs. What was the original velocity of the car? 3. A car travels west at a velocity of 22.0 m/s. It slows over 6.75 seconds to 8.00 m/s to avoid hitting a bald man holding a cardboard sign on a freeway off-ramp. His sign reads Bald.please help. What was the average acceleration of the car? What was the distance covered by the car in that time?
4 4. If a motorcycle (with a rider) is moving east along a road at 6.21 m/s, how long will it take it to reach a speed of 34.0 m/s if it has an average acceleration of 3.50 m/s 2?.
5 Arr, Ye Olde Quiz O Physics FOR FULL CREDIT SHOW ALL WORK SIG FIGS COUNT USE THE FORMULAS BOX THAT ANSWER 1. Kedge straps a rocket-powered jet pack to a shopping cart. He gets in the cart, ignites the engine and, from rest, accelerates west to a velocity of 289 m/s in 7.34 seconds, what is its average acceleration? What distance do Kedge and the cart travel during this time? 2. If a car is moving south at 6.23 m/s, how long will it take it to reach a speed of 28.8 m/s if it has an average acceleration of 2.53 m/s 2? 3. A rocket powered shopping cart traveling east, reaches a speed of m/s in 6.00 seconds after an average acceleration of 9.25 m/s 2 occurs. What was the original velocity of the cart?
6 4. True (T) or False (F) : A scalar quantity is magnitude/unit only. The speed of a plane can be described as 300 mi/hr East. An object can be moving and have an acceleration of zero. An objects motion tells you its speed and direction Displacement is a vector quantity. Acceleration can only occur if velocity is constant.

True (T) or False (F) : Motion can be described as a change in position If speed is constant, acceleration must be zero. The velocity of a car can be described as 60 km/hr to the North. A scalar quantity is magnitude/unit only. Acceleration is the rate of change of motion. Displacement is a vector quantity. 2. A rocket traveling east, reaches a speed of m/s in 8.08 seconds with an average acceleration of m/s 2. What was the original velocity of the rocket? 3. A bus travels west at a velocity of 32.0 m/s. It slows over 5.25 seconds to 19.0 m/s to avoid hitting a bald man holding a cardboard sign on a freeway off-ramp. His sign reads Bald.please help. What was the average acceleration of the bus? What was the displacement of the bus in that time?
