v=u+at
v=10+10×9 {a=f/M=100/10}
v= 10+90
v=100m/sec
final kinetic energy =1/2m×v×v
1/2×10×100×100
=50000kgm/sec
initial kinetic energy =1/2×m×v×v
=1/2×10×10×10
=500
v=10+10×9 {a=f/M=100/10}
v= 10+90
v=100m/sec
final kinetic energy =1/2m×v×v
1/2×10×100×100
=50000kgm/sec
initial kinetic energy =1/2×m×v×v
=1/2×10×10×10
=500
