In a particular crash test, a 1623 kg Mercedes SLS collides with a wall. The SLS hits the wall with a velocity of vi = 17.0 m/s and leaves the wall with a velocity of vf = -1.50 m/s. If the collision lasts for 0.25 s, find: (a) the impulse, and (b) the force of impact.

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
