Question

a body of mass 1000 kg moving at a speed of 10 M per second with the speed of 50 M per second in 20 seconds calculate the force required to do so

Answer 1

m = 1000 kg

u = 10 m/s

v = 50 m/s

t = 20 s

a =(v-u)/t

  = (50-10)/20

  = 40/20

  = 2 m/s²

F = ma

   = 1000*2

   = 2000 N

Answer 2

HEY MATE HERE IS YOUR ANSWER

mass m =1000kg

initial velocity u =10m/s

final velocity V =50m/s

time t =20s

force F =rate of change of momentum  

F=m(v-u)/t

F=1000(50-10)/20

F=1000x40/20

F=2000N
