- (a) A daredevil is attempting to jump his motorcycle over a line of buses parked end to end by driving up a 32° ramp at a speed of 40.0 m/s (144 km/h). How many buses can he clear if the top of the takeoff ramp is at the same height as the bus tops and the buses are 20.0 m long? (b) Discuss what your answer implies about the margin of error in this act—that is, consider how much greater the range is than the horizontal distance he must travel to miss the end of the last bus. (Neglect air resistance.)A stuntman tries to jump from a ledge over an 8 m gap onto a mattress that is 3 m below the current position. To do so, the stuntman runs to the edge of the ledge at a constant speed and leaps off in the horizontal direction with this speed. Describe your strategy to find the minimum speed with which the stuntman needs to run to land on the mattress Group of answer choices a) Find t from the vertical position equation. With this t, solve horizontal position equation to obtain v_initial b) Find t from the vertical velocity equation. With this t, solve horizontal position equation to obtain v_initial. c) Find t from the vertical velocity equation. With this t, solve horizontal velocity equation to obtain v_initial. d) Find t from the vertical position equation. With this t, solve horizontal velocity equation to obtain v_initialA roof worker loses his grip on his box of tools while working on a tall house. His box slides down the roof. The roof is angled at 29 degrees with the horizontal. The roof is made of a frictionless material. The box travels 5 m down the roof and then leaves the edge of it 12 m above the ground. a). Figure out the box's velocity as it leaves the house's roof? b). How far from the base of the house does the box hit the ground? c). By how much does the box clear the yard fence which is 1.8m tall and located 6.7m away from the base of the house? I TOOLS 5m 29° 12 m 1.8m 6-7m ENGL
