rosina flicks a ball horizontally from the top bunk of her bunk bed ,2.58m from the floor. the super ball lands on the the floor ,1.36m from the edge of the bed. calculate the velocity of the super ball as it left the bed

The eel has a certain amount of rotational kinetic energy when spinning at 14 spins per second. if it swam in a straight line instead, about how fast would the eel have to swim to have the same amount of kinetic energy as when it is spinning?

Six solutions are made, each with a y concentration of 1.0 μm and varying concentrations of ab as shown below. based on the concentrations, rank the solutions in decreasing order of reaction rate.

What kind of simple machine is a catapult?
