1)the cart has a mass of 50kg it moves with a speed of 35cm/sec.
*)find the speed of cart in m/sec.
*)find the kinetic energy of the cart?
2)an IGCSE student was calculating the power of the cart.he wanted to apply the formula of power.which formula did he use?
1. Can you convert cm/sec to m/sec?
Kinetic energy is (1/2)MV^2.
Calculate that with the speed V in m/s.
2. Unless the cart is doing work, it is delivering zero power. You don't need a formula for that.
