a 200g particle gains a momentum of 25Ns in 12 starting from rest. find the kinetic energy of the particle and the applied force.
is it correct i solve it using:
p=mv
i get v=125m/s
then i use KE=1/2mv^2
i get KE=1562.5kg m/s
then,i use I=ft
i get f=2.083N
is it correct?? i think there is have an error in my calculation..
