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?

A stone of mass 0.750 kg is launched vertically upward, from the ground, with an initial velocity of 18.0 m/s. (a) Determine the average power consumed by the gravitational force during the time it moves from the ground to 12.0 m above the ground? (b) Determine the instantaneous power being consumed by gravity when it first reaches 12.0 m above the ground?

A stone thrown downward with an initial velocity of 34.3 m/sec travel a distance of s meters, where: s(t)=4.9t + 34.3t and t is in seconds
A stone thrown downward with an initial velocity of 34.3 m/sec travel a distance of s meters, where:s(t)=4.9t + 34.3t and t is in seconds. If a stone is thrown downward at 34.3m/sec from a height of 294 m, how long will it take the stone to reach the ground?I am putting 294 in for t and trying to solve it that way. Is this correct? If not please let know where I am going wrong.
