# If the velocity versus time graph of an object is a straight line making an angle of 30 degrees with the time axis, the object is A) moving with constant non-zero speed. B) moving with constant non-zero acceleration. C) at rest. D) moving with infinite speed. E) none of the above.The area under a curve in a velocity versus time graph gives A) distance traveled. B) displacement. C) speed. D) velocity. E) acceleration.A car moving initially with velocity v0 with deceleration a comes to a full stop after traveling a distance d. We can say that the velocity of the car after traveling a distance d/2 is A) greater than v0/2. B) equal than v0/2. C) smaller than v0/2. D) has no relationship to v0.A car traveling with velocity v is decelerated by a constant acceleration of magnitude a. It travels a distance d before coming to rest. If its initial velocity were doubled, the distance required to stop would A) double as well. B) decrease by a factor of two. C) stay the same. D) quadruple. E) decrease by a factor of four.
