Combining Conservation Law A 15.0kg block is attached to a very light horizontal spring of force constant 500.0N/m and is resting on a frictionless horizontal table. Suddenly it is truck by 3.00kg stone traveling horizontally at 8.0m/s to the right, whereupon the stone rebounds at 2.00m/s horizontally to the left. Find the maximum distance that the block will compress the spring after collision.

An electric vehicle starts from rest and accelerates at a rate of 1.6 m/s2 in a straight line until it reaches a speed of 20 m/s. The vehicle after that slows at a constant rate of 1.4 m/s2 until it stops. (1) How much time elapses from start to s..
What is magnitude of the linear acceleration of the hoop . Elucidate using Newton's Second Law of Motion, why you can throw a golf ball further than a bowling ball, still though you throw both at the similar angle and with the same amount of force.
