In the worst-case scenario, you've got an elevator with a mass 2420 kg moving a speed 4.29 m/s when it reaches the bottom of the shaft. Your first idea is to put a spring, with spring constant 1.068×10⁴ N/m, at the bottom of the shaft.

a)Assuming the spring obeys Hooke's Law perfectly, how far will it compress to stop the elevator?

b)When the elevator comes to a stop with the spring compressed, what is the net force on the elevator?

c)It's a bit unreasonable to put a spring large enough to compresses this far under every elevator. So you decide to add a clamping mechanism to the walls around the spring, which will provide a friction force of magnitude 1.74×10⁴ N

Now how far does the spring get compressed?

Express your answer with appropriate units.

A truck with a mass of 1350 kg and moving with a speed of 12.0 m/s rear-ends a 821-kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Find the speed of both vehicles after the collision. vcar = ___________________ m/s vtruck = ____________________ m/s
