Suppose you throw a ball with mass 0.40 kg against a brick wall (Figure 1). It hits the wall moving horizontally to the left at 30 m/s and rebounds horizontally to the right at 20 m/s. Find the impulse of the force exerted on the ball by the wall. If the ball is in contact with the wall for 0.010 s, find the average force on the ball during the impact. Figure 1 of 2 Part A - Practice Problem: Suppose, rather than throwing a ball, you throw a lump of clay with mass 0.55 kg and initial velocity 30 m/s. When it hits the wall, the lump of clay sticks to the wall. Find the average force exerted on the wall by the lump of clay if it comes to a stop in 0.010 s. Express your answer with the appropriate units. F = UnitsSuppose you throw a ball with mass 0.40 kg against a brick wall (Figure 1).

An m1 = 2.0 kg steel ball is initially moving to the right at a velocity of v14 = +10 m/s. The ball strikes an m2 = 3.0 kg steel ball that is initially at rest. The collision is elastic. After the collision, the velocity of m1 is v1f = −2.0 m/s. (a) What is the velocity of m2 after the collision, i.e. v2f? (b) How much kinetic energy did the ball with mass m1 lose? Equation: (a) m1v1i + m2v2i = m1v1f + m2v2f (b) In general, kinetic energy, K = 12 mv2 (a) v2f = −6.0 m/s (b) KE lost = 54 J (a) v2f = +8.0 m/s (b) KE lost = 96 J (a) v2f = +4.0 m/s (b) KE lost = 96 J (a) v2f = +10 m/s (b) KE lost = 75 J (a) v2f = +7.0 m/s (b) KE lost = 84 J

Three carts (1, 2 and 3 from left to right) with masses m1 = 6.5 kg, m2 = 2.6 kg and m3 = 1.5 kg are on a frictionless surface as in the figure below. Cart 1 is initially moving to the right at speed v0 = 3.9 m/s, while carts 2 and 3 are initially at rest. Cart 1 hits carts 2 , and after this first collision, cart 2 (now moving to the right) eventually hits cart 3 . All collisions are perfectly elastic. What is the final speed of cart 3? a. 4.95 m/s b. 6.34 m/s c. 3.53 m/s d. 7.07 m/s e. 1.77 m/s
