A body is projected with an initial velocity of ( 8 i ^ + 6 j ^ ) m s - 1 . The horizontal range is ( g = 10 m s - 2 )

Question

A body is projected with an initial velocity of ( 8 i ^ + 6 j ^ ) m s - 1 . The horizontal range is ( g = 10 m s - 2 ), 9 . 6 m, 14 m, 50 m, 100 m

MARKS App · Accepted Answer

velocity = 8 i ^ + 6 j ^ v = 10 m s - 1 and angle tan θ = 6 8 = 3 4 Range = u 2 sin 2 θ g = u 2 2 sin θ cos θ g = 10 2 2 3 5 4 5 10 = 48 5 = 9.6 m
