Question

a certain force acting on a mass of 15 kg for 3 seconds give its velocity of 2 metre per second. find the magnitude of the force [give solution]

Answer 1

mass( m ) = 15 kg

time( t ) = 3 s

final velocity (v) = 2 m/s

initial velocity ( u ) = 0 m/s

force (F) = m*v-u\t

F = 15*2-0\ 3

F = 15* 2\3

F = 10 N
