- 1. Multiple Choice
A golf ball accelerates off a tee at 15m/s2, changing its velocity from 0m/s to 50 m/s down the fairway. How long did it take the golf ball to accelerate?750 seconds35 seconds0.3 seconds3.3 seconds - 2. Multiple ChoiceA ball of clay is thrown at a wall at a velocity of 28.0 m/s. After it hits the wall, it takes 0.020 s to stop. What is the acceleration of the clay when it hits the wall?1400 m/s2-1400 m/s20.56 m/s2-0.56 m/s2
- 3. Multiple ChoiceAcceleration is defined as the CHANGE intime it takes for one place to move to another place.velocity of an object.distance divided by the time intervalvelocity divided by the time interval
- 4. Multiple ChoiceWhy does a car accelerate as it round a corner at a constant speed?Its direction changesIt doesn'tIt slows downIts speeds up
- 5. Multiple ChoiceIn each of the following cases, determine where the car has no acceleration ?A car shortly after a stoplight turns green.A car approaching a red lightA car with the cruise control set at 80 km/hA car turning a curve at a constant speed
- 6. Multiple ChoiceWhich graph shows the object standing still?ABCD
- 7. Multiple ChoiceWhich graph demonstrates the greatest positive speed?ABCD
- 8. Multiple ChoiceWhich graph represents zero acceleration (constant velocity)?ABCD
- 9. Multiple ChoiceWhich graph represents the greatest acceleration?ABCD

- 17. Multiple ChoiceA block slides down a ramp starting at rest for 1.75 seconds with constant acceleration. If its final speed is 0.75 m/s, what is its acceleration?
What equation is most useful in solving this?d=stx=0.5at^2+x0x=((vi+vf)/2)*t + x0vf = at + vi - 18. Multiple ChoiceA block slides down a ramp starting at rest for 1.75 seconds with constant acceleration. If its acceleration is 0.63 m/s^2, how far did it go?
What equation is most useful in solving this?d=stx=0.5at^2+x0x=((vi+vf)/2)*t + x0vf = at + vi - 19. Multiple ChoiceA block slides down a ramp starting at 1.5 m/s for 1.75 seconds with constant acceleration. If its final speed is 0.75 m/s, how far did it move?
