Answer:
Explanation:
initial velocity, u = 28 m/s
Angle of projection, θ = 30°
The acceleration in horizontal direction is zero, so the horizontal component of velocity is constant.
Horizontal component of velocity, u cos θ = 28 x Cos 30 = 24.25 m/s
At t = 2 sec, the horizontal component of velocity = 24.25 m/s
At t = 3 sec, the horizontal component of velocity = 24.25 m/s
