work done will be change in kinetic nergy = 150000 joule
power will be 1250 joule per second
power will be 1250 joule per second

Could I get the method of solving this problem?
first convert velocity and time into m/s and second after that work done is equal to change in kinetic energy and power is equal to work/time
