(Points: 1) An airplane in level flight at an altitude of 0.6 km and a speed of 287 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)
(Points: 1) A ball is thrown horizontally from the top of a 51-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
(Points: 1) A stone is thrown upward from the top of a 90.2-m high building with an upward velocity component of 41.7 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.)
An airplane in level flight at an altitude of 1.1 km and a speed of 281 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)
حول:
1.1kg = 1100 m
281 km/h = 78.05
عوض فالمعادلة اللي موجوده بالورقه اللي كتبتها يطلع لك ان y2 - y1 = 1100
v1*t=0
وبكذا تكون سويت الخطوة الاولى ولقية ال t
عوض الحين فالمعادلة الثانية اللي كاتبها انا بال t اللي طلعته قبل شوي : d=v0*t
v0= 78.05
هذا السؤال الاول
