For general projectile motion, when the projectile is at the highest point of its trajectory, its acceleration is zero?

A)The horizontal and vertical components of its velocity are zero.

B) Its velocity is perpendicular to the acceleration.

C)The horizontal component of its velocity is zero.

D)Its velocity and acceleration are both zero.

A common graphical representation of motion along a straight line is the v vs. t graph, that is, the graph of (instantaneous) velocity as a function of time. In this graph, time is plotted on the horizontal axis and velocity on the vertical axis. Note that by definition, velocity and acceleration are vector quantities. In straight-line motion, however, these vectors have only a single nonzero component in the direction of motion. Thus, in this problem, we will call the velocity and the acceleration, even though they are really the components of the velocity and acceleration vectors in the direction of motion, respectively. Here is a plot of velocity versus time for a particle that travels along a straight line with a varying velocity. Refer to this plot to answer the following question.

What is the average acceleration of the particle over the first 20.0 seconds?
