A light spring-gun projectile launcher is mounted on an 0.453 kg air track glider. The gun points upward at an angle of 32 o with the horizontal track. With the glider at rest, a 61.3- g projectile is fired from the gun with a speed of 2.99 m/s. What is the speed of the air-track glider after the gun is fired?
define the magnitude of the torque on the dipole.
A wooden raft has a mass of 45 kg. When empty it floats in water (density 1000 kg/m3) with 68% of its volume submerged. What mass of sand could be put on the raft without it sinking.
A ball is thrown straight upward. At 5.50 m above its launch point, the ball's speed is one-half its launch speed. What maximum height above its launch point does the ball attain?
A rocket is launched at an angle of 57.0° above the horizontal with an initial speed of 99 m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 30.0 m/s2. At this time, its engines fail and the rocket proceeds ..
