Question

a body of mass 1.5 kg is moving along a straight line with a uniform velocity of 5m per second a constant force of 6 Newton acts on it perpendicular to the initial direction of motion for 3 seconds find the velocity of the body at the end of 3 second

Answer 1

it is the solution of your physics numerical.

Answer 2

here force is 6 Newton's , mass is 1.5 kg , initial velocity is 5m and time is 3 seconds. as you know F=ma applying this formula we get a as 4 again using first equation of motion which is v= u + a×t applying this we get v as 17m so answer is 17m
