Question

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

G1 Physics · Accepted Answer

From vertical motion, the time of flight is t = 10 s. Horizontal speed remains 98 m/s, so horizontal distance from the foot of the hill is x = ut = 98×10 = 980 m.
