A 0.38kg particle has a speed of 2.0 m/s at point A and kinetic energy of 7.5 J at point B.
(a) What is its kinetic energy at A?
J
(b) What is its speed at point B?
m/s
(c) What is the total work done on the particle as it moves from A to B?

a,b) KE= 1/2 mass*v^2
c) the work done is the difference in energies at A,B
