Answer:
D) NONE OF THESE
Explanation:
- velocity vertically = V sinθ
= 50 sin 53°
= 50 × 4/5
= 40 m/s
- velocity horizontally = V cosθ
= 50 cos 53°
= 50 × 3/5
= 30 m/s
- velocity is minimum at the highest point where vertical velocity is zero so it only has horizontal velocity.
velocity minimum = V cosθ
= 50 cos 53°
= 50 × 3/5
= 30 m/s
