A ball of mass 0.300kg that is moving with a speed of 5.4m/s collides head-on and elastically with another ball initially at rest. Immediately after the collision, the incoming ball bounces backward with a speed of 3.9m/s .
1) Calculate the velocity of the target ball after the collision.
2) Calculate the mass of the target ball.
A brick is thrown vertically upward with an initial speed of 4.90 m/s from the roof of a building. If the building is 98 m tall, how much time passes before brick lands on the ground.
A hotel elevator ascends 140 m with a maximum speed of 5.80 m/s. Its acceleration and deceleration both have a magnitude of 1.50 m/s2.
A typical lightbulb in your house is rated 200 W, which means that the bulb dissipates 200 W when connected to a DC voltage of 110 V. (a) What is the current through the lightbulb? (b) If the voltage is reduced to 55 V, what is the dissipated powe..
Find the angle of the first order maximum. what horizontal distance does it travel before it lands on building.
When the projectile is at the top of its trajectory, an internal explosion causes it to separate into two fragments of equal mass. One of the fragments falls straight downward as though it had been free from rest.
