Question:

A ball of mass m=2kg is thrown straight up into the air with an initial speed v0 =10 m/s. There is a constant air resistance of 2N acting on the ball to slow it down. Find the net work done in rising to its max height Use energy methods to find the maximum height it rises to Find the change in the gravitational energy of the ball Use Impulse momentum to find the time to rise to its maximum height Use the 2nd law and five formulas to find the maximum the height it rises to Use the 2nd law and five formulas to find the time to rise to its maximum height
