please help, I really appriciate you help alot.
Question:A 0.34 kg 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?
(b) What is its speed at point B?
(c) What is the total work done on the particle as it moves from A to B?
a) KE=1/2 mv^2
c) work = keatB - keatA
