An inquisitive physics student and mountain climber climbs a 51.0-m-high cliff that overhangs a calm pool of water. He throws two stones vertically downward, 1.00 s apart, and observes that they cause a single splash. The first stone has an initial speed of 2.06 m/s. (b) What initial velocity must the second stone have if the two stones are to hit the water simultaneously?
Daredevil is attempting to jump his motorcycle over a line of buses parked end to end by driving up a 46degree ramp leaning on the leftmost bus, reviving at a speed of 34.10 m/s. How long would the stunt last? How many buses can he clear if the top of the takeoff ramp is at the same height as the bus, 3.00m, and the buses are 8.75 m long?
