Q1. A stone thrown upward from the top of a 108 ft cliff at 132 ft/sec eventually falls to the beach below. (For this problem take the acceleration because of gravity to be -32 ft/sec; take upwards to be a positive direction.)
a.) How long does a stone take to reach its highest point?
b.) What is its greatest height?
c.) How long before the stone hits the beach?
d.) What is velocity of the stone on impact?
Q2. Displacement d1 is in the yz plane 52.0° from a positive direction of the y axis, has a positive z component, and has a magnitude of 4.50 m. Displacement d2 is in the xz plane 30° from the positive direction of the x axis, has a positive z component, and has magnitude 1.10 m.
