At the topmost point of a trajectory, its velocity and acceleration are an angle of

A

`0^(@)`

B

`45^(@)`

C

`90^(@)`

D

`180^(@)`

Text Solution

Verified by Experts

The correct Answer is:
C
(c):
At uppermost point (or highest point ), `v_(x)` is acting in the direction of `+X`-axis while `v_(y)` is zero, and acceleration is acting in the direction of negative Y-axis . So, both are perpendicular to each other.
