a force acts on a partical of mass 200g.the velocity of the partical changes from 15m/s to 25m/s in 2.5s. assuming the force to be constant, find its magnitude

u= 15 m/s
v= 25m/s
t = 2.5s
mass= 200g= 200/1000 = 0.2kg
...
Force = m(v-u/t)
F = 0.2(25-15/2.5)
F = 0.2×4
F = 0.8N
v= 25m/s
t = 2.5s
mass= 200g= 200/1000 = 0.2kg
