When a 0.20-kg mass is suspended from a vertically hanging spring, it stretches the spring from its original length of 3.0 cm to a total length of 7.0 cm. The spring with the same mass attached is then placed on a horizontal frictionless surface. The mass is pulled so that the spring stretches to a total length of 10.0 cm; then the mass is released and it oscillates back and forth. What is the maximum speed of the mass as it oscillates?
A 0.65kg block of ice is sliding by you on a very slippery floor at 3 m/s. As it goes by, you give it a kick vertical to its path. Your foot is in contact with the ice block for 0.003 seconds.
