The phenomena: Three rocks of equal mass are thrown with identical speeds from the top of the same building (identical height).
The phenomena: Three rocks of equal mass are thrown with identical speeds from the top of the same building (identical height). Rock X is thrown vertically downward, rock Y is thrown vertically upward, and rock Z is thrown horizontally. The Question: Which rock has the greatest speed just before it hits the ground? Assume air resistance is negligible. a) Make a prediction based on your prior experience. b) Does the question involve parameters that you know to be indicators of the change in...

An object of mass 0.500 kg is released from the top of a building of height 4.00 m. The object experiences a horizontal constant force of wind-(-2.001)N due to the wind blowing. Use the standard rectangular coordinate system with the +x axis to the right, +y axis vertically up, and +z axis coming out toward you. Take the origin of the coordinate system to be at the point of release of the object. (a) Find the time it takes for...

From the top of a 20 m tall building (its a two story building) you throw a rock, releasing it at a height level with the top of the building and with the rock going 6.0 m/s at 30 ° below the horizon- tal. What is the y-component of the velocity of the rock when it reaches a speed of 12 m/s, and how high above the ground is it at that instant? Answer is -11m/s and 14 m, but...

In outer space, far from any other influences, two rocks collide and bounce off each other. All motion is along the x axis. Rock A has a mass of 3 kg, an initial velocity of 〈40,0,0〉m/s, and a final velocity of 〈16,0,0〉m/s. Rock B has a mass of 6kg and an initial velocity of 〈−20, 0, 0〉 m/s. (a) What is the final 3-D velocity vector (not speed!) of Rock B? (b) What is the change in the total kinetic...

A large rock is released from rest from the top of a tall building. The average speed of the rock during the first second of the fall is 5 m/s. What is the average speed of the rock during the next second? (In this question we use the approximate value of 10 m/s2 for the gravitational acceleration.)

Two rocks are thrown from the top of a very tall tower. One of them is thrown vertically up with an initial velocity of Vup=19.7 m/s. The other rock is thrown horizontally to the right with an initial velocity of Vright 12.7 m/s. (See figure.) How far will the rocks be from each other after 2.76 s? (Neglect air resistance and assume that the rocks will not hit the ground or the tower.)
