The airplane is in level flight at an altitude of 0.50 km and a speed of 150 km/h. At what distance d should it release a heavy bomb to HIT the target X?First we should find out how MUCH time it takes.This means the time it takes to FALL those 500 meters. It starts at speed 0 vertically. 500=10t22 so t=10 seconds.Now the speed of 150 km/h should be expressed in meters per second. Divide that by 3.6. 150/3.6=41.66... or about 41.67. Now take this tenfold, you get 416.67. Rounding to 2 significant figures instead of 5 gives 420. But why it only asked for 2 significant figures it's weird.A ball is thrown horizontally from the top of a 20-m high hill. It strikes the ground at an angle of 45◦. With what speed was it thrown?Large cannon is fired from the ground level over level ground at an angle of 30 degrees above the the horizontal. The muzle speed is 980 m/s. Neglecting air resistance, the projectile will travel what horizontal distance before striking the ground?A stone is thrown outward from the top of a 59.4m high cliff with an UPWARD velocity component of 19.5m/s. How long is the stone in the air?A racing car traveling with constant acceleration increases its speed from 10m/s to 50m /s over a distance of 60m. How long does this take?An aeroplane is flying horizontally at an altitude of 2 km with 324 km/h. How far from the target should a bomb be released, so that it WOULD hit the target?A bomb is dropped from an aeroplane in level flight at a speed of 40m/s at a height of 490 m above the ground. How far ahead of the point of dropping does the bomb hit the ground (g=9.8m/s)?A stone is thrown upward from the top of CA = 59.5 on a high cliff with an upward velocity component of 19.6 m/s. How long is stone in the air?An aeroplane traveling horizontally at 78 meters per second at a height of 210 m drops a bomb to hit the target. At what horizontal distance from the target should the bomb be dropped?A bomb dropped from an aeroplane in level flight hits a target on the ground, which is 500 m ahead of the point of dropping. If the speed of the aeroplane is 50 m/s, what is its height at which it was flying?What is the time that the stone stays in the air in second if it is thrown outward from the top of a 59.4 m high cliff with an upward velocity component of 19.5 m/s?A ball is thrown horizontally from the top of a 20-m high hill.
