A car of mass 50KG accelerated from rest to 45ms-1 in 5secs. What net force must have been applied to produce this acceleration??


can u show me the working out and formula please^^

 

[pillar]

force = mass x acceleration

acceleration = velocity/time

therefore

acceleration = 45/5 = 9 m.s-2

net force = 50 x 9 = 450 N
