Q3. Figure Q3 shows a 1000 kg car hits a 4000 kg lorry. The car and truck has an initial velocity of 30ms-1 and 10ms¬1, respectively. Suppose both vehicles move together after the collision, determine: (a) the common velocity of both vehicles just after the collision. (b) the impact force on the car if; (i) the car has a good crumble zone (0.3 s impact time). (ii) the car has a weak crumble zone (0.1 s impact time). (c) Give a brief comment based on the forces obtained in the above cases.

Choose the correct answer of the following questions: 1. If no external impressed force acts on the system, the total momentum (G) of a system ... c. remains constant a. increases b. decreases d. none of the these 2. Which of the following cases momentum is conserved? (1 M) a. Perfectly elastic impact d. Momentum is always conserved c. Perfectly inelastic impact b. plastic impact with 0
is the following statement true? If not, why? Within the system, both the momentum and kinetic energy are conserved during each of the collisions ( spring-loaded elastic, hoop spring, and putty collisions).

d2 d₁ A Ad₁ VA = A small cylinder with a weight of 10 lb is dropped from an initial height of d₂: 3 ft from rest. The spring has an unstretched length of lo = 12 inches and a spring constant of k = 30 lb\inch. The spring is intially compressed by small ropes to a length d₁ = 6 inches. = k What is the maximum additional distance the spring compresses after the cylinder lands on the platform? Assume the platform and spring are massless in this calculation. inches
A boxer delivers a hard blow to the chin of his opponent. The inertia of the boxer's hand (with glove) and forearm is 3.0 kg, and the inertia of the opponent's head is 6.5 kg. You learned in neurobiology class about 10 J of extra internal energy will render an opponent wobbly - kneed, and you guess that about half of the converted energy will end up in the opponent's head. Assuming a coefficient of restitution e = 0.20, with what speed does the boxer's fist have to contact the opponent's head in order to deliver the punch?

The force exerted on a car by a prototype crash barrier crash is F=-(4400 + 50000S) N, where S in the distance in meters from the initial contract. Suppose that you want to design the barrier so it can stop a 2400kg car traveling at 100kph. Determine the average power transferred from the car during the impact if the duration of impact of the car is 0.33 sec.
