Transcribed Image Text:5 m/s 1 m Figure Q3
The 10 kg wooden box A with a speed of 5 m/s as shown in Figure Q3 is 1 m from the
stationary 10 kg Box B. Given the coefficient of kinetic friction between the floor and the
two crates is uk = 0.6, and the coefficient of restitution of the impact is e = 0.5.
(a)
Find wooden box A speed just before the impact.
(b)
Calculate both box A and B speed after the impact.
(c)
Determine how far will box B moves from its initial position as the result of the impact.
