Question

A projectile is fired horizontally with a velocity of 98 m/s from the top of a hill 490 m high. Take g = 9.8 m/s². Find the distance of the target from the foot of the hill (m).

G1 Physics · Accepted Answer

The horizontal component remains 98 m/s throughout the flight. With time of flight 10 s, horizontal distance = 98×10 = 980 m.
