Question

A projectile is thrown at an angle of 30° to the horizontal with velocity of 20 m/s.
Calculate i) horizontal range. ii) time of flight. ( Assume g = 10 m/ s)

Answer 1

Answer:

34.64 m

2 second

Explanation:

time of flight =(2×20/2)/10=2 second

horizontal range =(400×(3^1/2)/2)/10=34.64 m
