A dynamite blast at a quarry launches a chunk of rock straight upward, and 2.1 s later it is rising at a speed of 20 m/s. Calculate its speed (a) at launch and (b) 4.2 s after the launch. Let's model this situation as if it's a case of constant acceleration of 9.8 m/s downward at launch at 4.2 s after launch m/s

A rock is thrown straight vertically upward with an initial velocity of 15 m/s. Ignore energy lost to air friction. The rock will rise to a maximum height of The velocity of the rock at half that maximum height is A Hooke's law spring is compressed 12 cm from equilibrium and the potential energy stored is 3.6 J. The spring constant in this case is The spring is then used to launch a mass of 50 gram along a frictionless...
