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.
