A 75-kg man is riding in a 75-kg cart at 1.0 m/s. He jumps off in such a way as to land on the ground with no horizontal velocity. The resulting speed of the cart is:
A coin is tossed upward with an initial speed of 7.5 m/s2, What is the total time it is in the air before returning yo it's releasing point
Under the influence of its drive force, a snowmobile is moving at a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt.
From the shape of total energy vs. time plot, what can you conclude about the conservation of mechanical energy in your mass and spring system.
Light is incident on a slit 0.750 mm wide. On a screen 2.00 m away, the distance from the central maximum to the first minimum is 1.35 mm. compute the wavelength of the light.
A 12 kg box slides 4.0 {rm m} down the frictionless ramp, and then collides with a spring whose spring constant is 240 N/m.
If the weight of a room full of water is so great, why don't the first floors of houses built over basements all collapse as flooded to the ceiling.
From the shore, you observe a buoy in the ocean rising and falling with the waves. You determine it takes 5 s for the buoy to go down and up again, Approximately how fast are the waves moving

A baseball is hit at ground level. The ball reaches its maximum height above ground level 3.0 s after being hit. Then 2.5s after reaching its maximum height, ball barely clears a fence that is 97m from where it was hit. Suppose the ground is level..
A ball is placed on an edge of a cliff and it is kicked by a soccer player at 20.0 m/s at an angle of ? = 30? above the horizontal, Find the height of the cliff
Two horizontal curves on a bobsled run at the similar angle, but one has twice the radius of the other. The safe speed (no friction needed to stay on the run) for the smaller radius to curve is v. What is the safe speed on the larger radius curve.
A jetliner is moving at a speed of 258 m/s. The vertical component of the plane's velocity is 85.8 m/s. find the magnitude of the horizontal component of the plane's velocity.
