A 5 kg ball collides head-on with a 10 kg ball, which is initially stationary. The collision is inelastic. Which statement is true?
a) the magnitude of the change of velocity the 5 kg ball experiences is less than that of the 10 kg ball.b) the magnitude of the change of velocity the 5 kg ball experiences is equal to that of the 10 kg ballc ) the magnitude of the change of velocity the 5 kg ball experiences is greater than that of the 10 kg balld) the magnitude o the change of the momentum of the 5 kg ball experiences is greater than that of the 10 kg balle) two of the above statements are true
Kinetic energy KE has dimensions kg · m^2/s^2. It can be written in terms of the momentum p and mass m as KE=p^2/2m. (a) Determine the proper units for momentum using dimensional analysis. (Use the following as necessary: kg, m, and s.)
