Problem 2: Doctor Horrible launches a projectile at Captain Hammer as he stands on top of a building. The projectile is launched from a launcher with an initial velocity of 51.0m/s at an angle of 53.0° above the horizontal. After the projectile reaches its maximum height and begins to descend, it lands next to Captain Hammer on top of a building that has a height of 18.5m. a) How long does it take for the projectile to land on top of the building? b) What is the velocity of the projectile just before it strikes the roof of the building?

A 4.0 kg projectile is launched into the air with an initial velocity of 15 m/s at an angle of 30° above the horizontal. When the projectile reaches its maximum height it explodes, splitting in two parts, one of mass 3.0 kg and one of mass 1.0 kg. Assume the explosion was essentially instantaneous. Determine the maximum height of the projectile using energy. After the explosion, if the 1.0 kg mass is moving at 1/2 the speed it was right...

I have a physics problem that gives me a projectile launched. It tells me the angle above horizontal, the MINIMUM speed while in flight, and the amount of meters the ball traveled when it lands. The question asks for max height. What's tripping me up is this MINIMUM velocity. Where on the projectile is the velocity a minimum. I was thinking the minimum velocity would be at the highest point, because at the highest point the velocity is 0, however,...
