You throw a 0.5 kg rock upward from your hand (which is 1 m off the ground when the rock leaves it). The rock rises to a maximum height of 2.5 m and then falls past your hand to the ground. From the moment you let it go until the moment just before it lands, what can you say about the work that gravity does on the rock?

Group of answer choices

a. Gravity does negative net work on the rock.

b. Gravity does positive net work on the rock.

c. Gravity does no net work on the rock.

    You throw a 20-N rock vertically into the air from ground level. You observe that when it is a height 15.9 m above the ground, it is traveling at a speed of 24.8 m/s upward. A.Use the work-energy theorem to find its speed just as it left the ground. B.Use the work-energy theorem to find its maximum height.

    You throw your phone straight out horizontally so that is leaves your hand with a velocity of 15.6 m/s forward. When the phone leaves your hand, its vertical height is 1 m above the ground. Once it leaves your hand, it begins to fall while moving forward due to gravity pulling it downward. a. What is the phones initial velocity in the horizontal (forward) direction in the instant it leaves your hand? b. What is the phones initial velocity in...

    While standing at the edge of the roof of a building, you throw a stone upward with an initial speed of 7.39 m/s. The stone subsequently falls to the ground, which is 16.9 m below the point where the stone leaves your hand. At what speed does the stone impact the ground? How much time is the stone in the air? Ignore air resistance and take g -9.81 m/s. (This is NOT a suggestion to carry out such an experiment!)

    You throw a frisbee of mass m = 0.5 kg, and radius r = 0.1 meters, off of a hill, with initial translational speed of v0 = 5 m/s, from a height of h0 = 3 meters. The tangential speed of the edge of the frisbee is equal to the initial translational speed, and doesn't change as it travels through the air. Treat the frisbee as a solid disk, and ignore air resistance. a) What is the initial total Kinetic...
