1. Maria stands at the top of a 30 meter high cliff. She tosses a stone vertically up into the air, off the edge of the cliff, giving it an initial velocity of 8m/s. Consider the stone to be in free fall for the duration of its flight.
a) What is the location of Maria's stone 1.5seconds after it is thrown?
b) What is the maximum height, form the base of the cliff, reached by Maria's stone?
c) What is the stone's velocity when it hits the ground?
