Question

a force of 1.5 newton is applied on a ball of mass 150 gram for a time of 2 seconds. if it starts from rest what is its velocity when force ceases ?​

Answer 1

w.k.t

f = m/ a

so, f= 1.5 N and m = 150 g = 150/1000kg

a=? a= m/f

a = 0.15/1.5

a=10 power_1

here u=0

v = u + at

v=0+1/10×2

v =1/5m/s
