Mass = 1200 kg
Acceleration = 8 m/s^2
FORCE = Mass x acceleration
= 1200 x 8
= 9600 N
Work Done = Force x Displacement
= 9600 x 40
= 384000 Joule
Kinetic Energy = 1/2 x Mass x velocity ^2
Acceleration = 8 m/s^2
FORCE = Mass x acceleration
= 1200 x 8
= 9600 N
Work Done = Force x Displacement
= 9600 x 40
= 384000 Joule
Kinetic Energy = 1/2 x Mass x velocity ^2
