It leaves the track horizontally, flies through the air,andsubsequently strikes the ground. The acceleration of gravityis9.8m/s2.
A) What is the speed 'v' of the block as it leaves the track?Answerin units of m/s?
B) What is the horizontal distance 'x' the block travels throughtheair? Answer in units of m.
C) What is the total speed of the block as it hits theground?Answer in units of m/s.
