The center of mass of a proton with mass 1.673·10-27 kg and alpha particle with mass 6.645·10-27 kg is moving with a speed of 6.993×105 m/s. What is the speed of the proton in the laboratory frame where the alpha particle is at rest?
imagine the water is in freefall as it drops. What charge must be on each plate.
You're in an airplane that flies horizontally with speed 1000 km/h (280m/s) when an engine falls off. Neglect air resistance suppose it takes 30s for the engine to hit the ground.
The molecule has a rotational kinetic energy that is of the translational kinetic energy of its center of mass. What then is molecule's angular speed about the center of mass.
A 0.144 kg baseball is pitched horizontally at +38 m/s and after it is hit by the bat it moves horizontally at -38 m/s.
Your Industry has just developed a new sports drink that is in a container which will keep it cool for up to 6 hours. Develop a marketing plan for this product and then write a 3 page paper describing how you would market the product.

A parachutist descending at a speed of 10.0 m/s loses a shoe at an altitude of 30.0 m. (Assume the positive direction is upward.). Explain when does the shoe reach the ground? What is the velocity of the shoe just before it hits the ground?
A 10-kg box is stationary on the ground and pushed by a downward force of 30 N. Calculate the supporting normal force acted on the box from the ground
What is the amplitude of the oscillations . Could you think of a simple method for determining the focal length of a converging lens.
A gun shoots bullets that leave the muzzle at 213m/s. If a bullet is to hit a target 160.4m away at the level of the muzzle, the gun must be aimed at a point above target. (Neglect air resistance.)
define the magnitude of the initial velocity. use 9.81 m/s^2 for the acceleration due to gravity on earth.
suppose that the engineer is at x = 0 when, at t = 0, he first spots the locomotive. Sketch x(t) curves for the locomotive and high-speed train for the cases in which a collision is just avoided and is not quite avoided. Do this on paper. Your ins..
