Question

Q.An airplane in level flight at an altitude of 1.0 km and a speed of 382 km/h, releases a heavy bomb. At what horizontal distance d, from the point of release should the bomb hit the ground? Take g = 9.8m/s2. (Answer in SI units but do not write units with your answer)



Q2

A ball is thrown horizontally from the top of a 56-m high building. It strikes the ground at an angle of 45 degrees below horizontal. With what speed was it thrown? (Take the value of g = 9.8 m/s2) Answer in SI units but do not write units with your answer
Q3-

A stone is thrown upward from the top of a 51.9-m high building with an upward velocity component of 18.2 m/s. How long does it take for the stone to hit the ground? Take the value of g = 9.8 m/s2 (Give your answer in SI units but do not write units with your answer.)

Explanation / Answer

Q1 height h = 1*10^3 m speed u =382*(1000/3600) m/s              = 106.11 m/s horizontal distance R = u sqrt(2h/g)                                    = 106.11 sqrt(2*10^3/9.8)                                    = 1515.85 m u should not post more than one problem
