Question

Resultant force of 20N acts on an object of mass 4kg for 10m find the final speed if the initial speed is 5ms?

Answer 1

F=ma,

a=F/m,     a=20/4,     a=5m per square second

v=u+at,     v=5+5x10,     v=55ms

the answer is 55ms, where m=mass, a=acceleration, F=Force, v=final speed, u=initial speed, t=time
