A tennis ball of mass m rebounds from a racquet with the same speed v as it had initially. It's incident at angle theta from the normal and rebounds at the same angle. What is the magnitude of the momentum change of the ball?
Imagine that an object of mass m (m=2kg) has position vector r=(3t+5t^3)x where x is a unit vector. Calculate the work done on the particle over time interval 0 to 1 sec
