Q1. A 1035 kg car carrying four 78 kg people travels over a rough "washboard" dirt road with corrugations 5.0 m apart which causes the car to bounce on its spring suspension. The car bounces with maximum amplitude while its speed is 16 km/h. The car now stops, and the four people get out. By how much does the car body rise on its suspension owing to this decrease in weight?
Q2. A softball is tossed into the air at the angle of 60.0° with the vertical at an initial velocity of 11.0 m/s. What is its maximum height?
