The projectile was fired horizontally from a height of h = 25 meters above the ground at a speed of v0 = 250 m/s. How deep is the abyss (neglecting air resistance)? (gravitational acceleration g = 9.81 m/s² and the speed of sound in air v = 343 m/s) The stone fell into the abyss: 2 seconds after we heard it hit bottom. What is the maximum height of body reach?Ĭalculate car deceleration (as a multiple of gravitational acceleration g = 9.81 m/s²) when a vehicle in a frontal collision slows down uniformly from a speed 111 km/h to 0 km/h in a 1.2 meters trajectory. Body height versus time describes equation h = v 0 * t - (1)/(2) * 9.8 * t². The body was thrown vertically upward at speed v 0 = 39 m/s. At what horizontal distance from point B should be release any body from the aircraft body to fall into point B? (g = 9.81 m/s²) The aircraft flies at an altitude of 12600 m above the ground at a speed of 532 km/h. How long before we let the second body fall freely from the same height to hit the Earth simultaneously? We throw the body from a height h = 5 m above the Earth vertically upwards v0 = 10 m/s.

How long and at what speed does the body fall to the ground during a free fall from a height of 35 m? At impact, it took 2.0 seconds for the toy's velocity to reach 0 meters/second. The toy hit the ground at a velocity of 16.0 meters/second. Jeremy accidentally dropped his toy stuffed animal from the balcony of his apartment on the fourth floor.

How long does the stone fall freely into a depth of 80m? What speed will it hit the bottom of the abyss? How much kinetic energy did the elevator car have when it hit the ground floor of the building when the free fall of the car lasted 5 s? The elevator car weighing 720 kg, is torn off at the height of 125 m and begins to fall in a free fall.
