A cargo plane is flying horizontally at an altitude of 10.3 km
A cargo plane is flying horizontally at an altitude of 10.3 km with a speed of 920 km/h when a large crate falls out of the rear loading ramp. (Ignore any effects due to air resistance.)
(a) How long does it take the crate to hit the ground?
(b)How far horizontally is the crate from the point where it fell off when it hits the ground?
(c) How far is the crate from the aircraft when the crate hits the ground, assuming that the plane continues to fly with the same velocity?
Q2:The roof of a two-story house makes an angle of 26° with the horizontal. A ball rolling down the roof rolls off the edge at a speed of 5.9 m/s. The distance to the ground from that point is 6.9 m.(a) How long is the ball in the air?
(b) How far from the base of the house does it land?
(c) What is its velocity just before landing? (Let upward be the positive y-direction.)
