Part a- a block starts at rest and slides down a frictionless track. it leaves the track horizontally, flies through the air, and subsequently strikes the ground. the acceleration of gravity is 9.81 m/s 2. the mass of the block is 447g. the initial height of the track is 4m, while the final height of the track is 2.4m above the ground. what is the speed v of the ball when it leaves the track? answer in units of m/s. part b- what is the horizontal distance x the block travels in the air? answer in units of m. part c- what is the speed of the block when it hits the ground? answer in units of m/s.
