Let a force of 1500 Newtons act through a distance of 200 meters on a 1500 kg car which starts from rest.

a. What is the work done?

b. What is the final velocity?

c. What is the car's momentum?

d. What is the car's change in momentum?

e. What is the car's Kinetic Energy?

f. What is the car's change in Kinetic Energy?

  • physics -

    workdone=force*distanc
    1/2 mv^2=work done solve for v
    momentum=mv
    changemomentum=mv-m*0
    KE= workdone=1/2mv^2
    change in KE= 1/2 mv^2-1/2 m*0^2
