Question

Find the time after which the velocity vector will make an angle of 37° with the horizontal.

Answer 1

Given:

The velocity vector will make an angle of 37° with the horizontal.

To find:

Find the time after which the velocity vector will make an angle of 37° with the horizontal.

Solution:

The horizontal velocity of the projectile after time t = vcosθ

From given, we have, θ = 37°

Therefore, the time, t = v × cos 37° = 0.798v sec.
