Impulse pair in collision, that is an example of Newtons third law on two interacting objects. A 4 kg moving at +5 m/s collided with a 2kg object at -10 m/s.
Added by Anna E.
Step 1
- For the 4 kg object moving at +5 m/s: Momentum = mass × velocity = 4 kg × 5 m/s = +20 kg·m/s. - For the 2 kg object moving at -10 m/s: Momentum = mass × velocity = 2 kg × (-10 m/s) = -20 kg·m/s. Show more…

Pre- and post-collision information is shown. Identify the collision parameters that are consistent with the indicated change in momentum. (A + sign indicates a rightward direction; a - sign indicates a leftward direction.) v = 4 m/s v = 10 m/s 3 kg 3 kg Impulse = +14 N•s Impulse = +18 N•s Δp = +42 kg•m/s F = +18 N, Δt = 3 s F = +40 N, Δt = 3 s

Two particles A and B have mass 2m and km respectively. The particles are moving in opposite directions along the same straight smooth horizontal line so that the particles collide directly. Immediately before the collision A has speed 2u and B has speed u. The direction of motion of each particle is reversed by the collision. Immediately after the collision the speed of A is u/2. (a) Find, in terms of m and u, the magnitude of the impulse exerted by B on A in the collision. (b) Show that k < 5.

You push a 2 kg cart, giving it a speed of 2 m/s, moving in the negative direction. At the same time, your lab partner pushes a 3 kg cart, giving it a speed of 2 m/s, moving in the positive direction. The two carts collide but do not stick together. A sensor on the 3 kg cart states that it experienced an impulse of -6 kg*m/s. (a) Draw a side view diagram of the two carts just before the collision. Draw velocity arrows on each cart before the collision. Also, write the speed of each cart next to its velocity arrow. (b) What is the impulse that acted on the 2 kg cart? Impulse on 2 kg = _______________ (c) What is the velocity of each cart after the collision? v2kg' = _______________ v3kg' = ________________ (d) Assuming that the collision lasted for exactly 0.25 s, what was the average force vector acting on the 2 kg cart during the collision? FAvg = _______________
