... 7. A car starts from rest and accelerates 6 m/s2 for 5 s after which it travels with a constant velocity for 9 s. The brakes are then applied so that it decelerates at 4 m/s2. Find the total distance traveled by the car. 8. An object starts from rest and accelerates 4 m/s2. a) How far will it travel ...

Concept Summary
... o Acceleration changes the velocity (in magnitude, direction, or both). o Acceleration can speed you up or slow you down (often called deceleration). o Constant velocity means the acceleration is zero and visa versa. o Average acceleration = change in velocity/elapsed time vector quantity = magnit ...

... during which of the 4 seconds does the ball’s speed increase the most? • If you drop a ball from a height of 4.9 m, it will hit the ground 1 s later. If you fire a bullet exactly horizontally from a height of 4.9 m, it will also hit the ground exactly 1 s later. Explain. • If a golf ball and a bowli ...
