A golf ball is hit at ground level. The ball is observed to reach its maximum height above ground level 3.8 s after being hit. 0.68 s after reaching this maximum height, the ball is observed to barely clear a fence that is 738 ft from where it was hit. The acceleration of gravity is 32 ft/s^2. How high is the fence?
Important information about Physics - Mechanics A satellite of mass 205 kg is launched from a site on the Earth's Equator into an orbit at 175 km above the surface of Earth.
A 3.00 kg mass resting on a level table top is pulled along by a horizontal force of 16 N and accelerates at 4.00 meters per second per second. What is the force of friction between block and table.
A 4.00 kg model rocket is launched, expelling 46 g of burned fuel from its exhaust at a speed of 590m/s. What is the velocity of rocket after the fuel has burned? Hint: overlook the external forces of gravity and air resistance.

Use approximate calculations assuming constant current during the output pulse. Calculate the ampere-hour rating of the battery so it lasts for five years.
If the coefficient of friction between the book and the wall is .35, explain how hard would she have to push in order to allow the book to slide down at constant speed?
What is the tangential acceleration of a bug on the rim of a 13.0-in.-diameter disk if the disk accelerates uniformly from rest to the angular speed of 76.0 rev/min in 3.50 s.
A car is traveling at 43.2km/hr on a flat, concrete highway. If the brakes are applied such that skidding occurs, the kinetic coefficient of friction between the road and tires is 0.808. If anti-lock brakes are properly applied after that no skidd..
