1. A stone is thrown vertically upward with a speed of 24.0 m/s. (a) how fast is it moving when it is at a height of 13.0 m? (b) how much time is required to reach this height? 2. A helicopter is ascending vertically with a speed of 5.40 m/s. At a height of 105 m above Earth, a package is dropped from the helicopter. How much time does it take for the package to reach the ground?
A stone is thrown vertically upward with a speed of 18.0m/s. How fast is it moving when it reaches a height of 11.0m? How long is required to reach this height?Why are there two answers?
If a stone is thrown vertically upward from the surface of the moon with a velocity of 6 m/s, its height (in meters) after t seconds is h = 6t - 0.83t2. (Round the answers to two decimal places.) a. What is the velocity of the stone after 3 s? b. What is the velocity of the stone after it has risen 8 m?
3. A stone is shot up vertically in the air from the ground with an initial speed of 60 m/s. i) Calculate the height from the ground and the speed ofthe stone 7 seconds after It was shot. (ii) 7 seconds after the hot, is the stone moving upward or downward? Justify your (ii) Calculate the maximam height from the ground the stone will reach. 2.You ary at the top ofa 90 m ผ wer, you tossihp a' stone, Calculate...
A stone is thrown vertically upward with a speed of 12.0 m/s from the edge of a cliff 75.0 m high; (a) How much time does it take in order for the stone to reach the maximum height? (b) What is the maximum height measured from the edge of the cliff? (c) How much time (from the instant the stone is projected) does it take to reach the bottom of the cliff? (d) What is its speed just before reaching...
A stone is thrown vertically into the air from a tower 110 ft. high at the same time that a second stone is thrown upward from the ground. The initial velocity of the first stone is 60 ft/s and that of the second stone 85 ft/s. When and where will the stones be at the same height from the ground?
show work 4. Suppose a stone is launched vertically upward with initial velocity 32 ft/sec from a height of 48 ft above ground. After t seconds its height is given by s(t) = -16t2 + 32t + 48 At the time when the stone hits the ground it is moving with a speed of A. 32 ft/s B. 24 ft/s C. 64 ft/s D. 48 ft/s E. 96 ft/s
A balloon is moving vertically upward at a constant speed of 10 m/s. When the balloon is at a certain height h above the ground, a stone is thrown horizontally with a velocity of 6 m/s relative to a person at rest in the basket of the balloon. The stone is observed to hit the ground in 5 s. Find h A. 50 m B. 20 m C. 75 m D. 125 m E. 10 m
A stone with mass m = 0.700 kg is thrown vertically upward into the air with an initial kinetic energy of 610 J. The drag force acting on the stone throughout its flight is constant, independent of the velocity of the stone, and has a magnitude of 0.600 N. What is the maximum height reached by the stone? What is the speed of the stone upon impact with the ground?
From an elevated point A, a stone is projected vertically upward. When the stone reaches a distance h below A, its speed is triple of what it was at a height h above A. Show that the highest point reached by the stone above A is 5h/4.
