A bullet of mass mp = 3.54 g is fired at a block of mass mA = 1.22 kg stopped. It comes out sticks in a second mass block mB = 1.78 kg as well stop. After bumps the blocks have speed VA = 0.63 m/s and VB = 1.48 m/s. Calculate the bullet velocity before each impact. Calculate the pulse received from the projectile, from the mA and me masses and the loss of energy. A bullet of mass m = 4.54 g is fired at a mass block M = 2.41 kg stationary. After impact the two masses proceed with velocity V on a plane with rough constraint (μd = 0.21). Both masses stop after having covered a distance L = 1.83 m. Calculate the velocity of the bullet before the impact.
