Question

A baseball is thrown into the air from the outfield towards second base. When the baseball reaches its highest point above the ground, which of the following is a true statement? (A) Both the x- and y-components of the baseball's velocity are zero. (B) The baseball's velocity is not zero, but its acceleration is zero. (C) The baseball's velocity is perpendicular to its acceleration. (D) The baseball's acceleration depends on its initial angle when it was thrown into the air. (E) None of the above is true. b) Consider a football which has been kicked into the air from the ground at some initial angle theta, where 0 degree

Explanation / Answer

here,

1)

the baseball is thrown up in the air from the outfeild ground

at maximum height

the vertical component of the velocity is zero

and the ball is moving in horizontal direction, the ball has only x-component of velocity

and the accelation due to gravity is acting downwards

so, the baseball's velocity is perpendicular to its accelration

correct option is (C)
