On the Apollo 14 mission to the moon, astronaut Alan Shepard hit agojf ball with a 26 iron. The acceleration due to gravity on themoon is 1/6 of its value on earth. Suppose he hits the ball with aspeed of 26 m/s at an angle 36° above thehorizontal.
How much farther did the ball travel on the moon thanit would have on earth?
For how much more time was the ball in flight?
A total of 3.04 106 electrons are placed on an initially uncharged wire of length 1.23 m. find the magnitude of the acceleration of a proton
If the tension in each chain at the lowest point is 408 N, find the child's speed at the lowest point.
At time t = 0, a projectile is launched from ground level. At t = 2.00 s, it is displaced d = 56 m horizontally, what is its horizontal displacement D from the launch point

35g of copper pellets are removed from a 300C oven and immediately dropped into 80ml of water at 24C in an insulated cup. What will the new water temperature be
The wavelength of violet light is about 430 nanometers, or 4.30*10-7 m. The frequency of the violet light reflected from a metal surface and the frequency of the vibrating electron that produces it are the same.What is this frequency?
Consider a heat engine that operates between thermal reservoirs at 450 K and 232 K. Suppose the engine does 4500 J of work while it expels 90 J of energy to the cold reservoir. Is this engine possible in the real world
This demonstration is more complicated because it involves a vector. For a rotating wheel, the direction of the angular momentum, , is found by curving the fingers of your right hand in the direction of the rotation, your thumb then points along .
Compute your average velocity in the following two cases: (a) You walk 61.0 m at a speed of 2.26 m/s and then run 61.0 m at a speed of 3.38 m/s along a straight track. (b) You walk for 1.00 min at a speed of 2.26 m/s and then run for 1.85 min at 3..
