Question

whether the car will uppose a car is moving to the west. For each of the following cases, state speed up, slow down, or remain moving at the same speed. a. The acceleration of the car is zero. b. The acceleration of the car is to the cast c. The acceleration of the car is to the west. 4. Consider the velocity vs. time graphs for two objects. a Does either object ever turn around? If so, identify the Velocity, m/s time or times. Explain bricfly in cither case 10 Time, b. Is there a time when both objects are speeding up? If so, identify the time or times. Explain briefly in either case. Object B c. Is the acceleration of object B positive, negative, or zero at t-7s? Explain briefly 5. A velocity-time graph is shown for a cat moving along a fence. a. At which of the labeled points, if any, is the acceleration zero? 0 Explain briefly. Rank the magnitude of the acceleration of the cat at the points labeled A, B, C, and D. Explain how you determined your ranking. b.

Explanation / Answer

here,

2)

when the accelration is in opposite direction to the velocity , the car will slow down

when the accelration is in same direction to the velocity , the car will speed up

when the accelration is zero , the car will move with same velocity

a)

the car will move with same velocity

b)

the car will slow down

c)

the car will speed up
