What is the magnitude of the momentum of a 28 g sparrow flying with a speed of 8.4 m/s?

A 60 g tennis ball with an initial speed of 32 m/s hits a wall and rebounds with the same speed. FIGURE P11.40 shows the force of the wall on the ball during the collision. What is the value of F_max , the maximum value of the contact force during the collision?

Consider an electron undergoing cyclotron motion in a magnetic field. According to Bohr, the electron’s angular momentum must be quantized in units of ℏ. Find an expression for the allowed energy levels E_n in terms of ℏ and the cyclotron frequency f_cyc.

How fast would you have to throw a 150-g rock for it to have the same momentum as a 10-g sniper rifle bullet traveling at 900 m/s?
