Stuck in the middle of a frozen pond with only your physics book, you decide to put physics in action and throw the 3.75-kg book. If your mass is 60.9 kg and you throw the book at 13.1 m/s, how fast do you then slide across the ice? (Assume the absence of friction.)
A monatomic ideal gas is held in a thermally insulated container with a volume of 0.0850m^3 . The pressure of the gas is 105kPa , and its temperature is 357K a)To what volume must the gas be compressed to increase its pressure to 150kPa b)At what ..
As you bounce a tennis ball of mass 7.70 10-2 kg off a wall, its velocity changes from vx = 10.8 m/s to vx = -8.3 m/s. Find the impulse applied to the ball
A block slides down an inclined plane, starting from rest and being pushed with a constant acceleration of 4.60 m/s2 over the distance of 20.80 cm. It then decelerates at the constant rate of 1.03m/s2 (because of friction), until it again comes to..
As part of a safety investigation, two 1800 cars travelling at 18 are crashed into different barriers. Find an average forces exerted on (a) car that hits a line of water barrels and takes 1.80 to stop, and (b) car that hits a concrete barrier and ta..
A simple circuit consists of a light bulb connected to the terminals of a battery. Determine the resistance and power of the bulb
