Friction and Kinetic Energy

You are a world-famous physicist-lawyer defending a client who has been charged with murder. It is alleged that your client, Mr. Smith, shot the victim, Mr. Wesson. The detective who investigated the scene of the crime found a second bullet, from a shot that missed Mr. Wesson, that had embedded itself into a chair. You arise to ...continues

It's a Math Problem in Science (FORCE, MASS, ACCELERATION)

F=MA F= Force (measured in Newton's) M= Mass (measured in Kilograms) A= Acceleration (measured in Meters per second per second) (m/s²) What is the answer? 1. F= _________ where; M = 100Kg and A = 5 m/s² F= MxA F = ___________X ________ = ______________ 2. F= _________ where; M = 10Kg and A = 50 m/s² F ...continues

Calculating the Resultant Force on the Passenger of a Rotating Amusement Park Ride

In an amusement park ride called The Roundup, passengers stand inside a 19.0m-diameter rotating ring. After the ring has acquired sufficient speed, it tilts into a vertical plane, as shown in the figure (see attachment). A. Suppose the ring rotates once every 4.70s. If a rider's mass is 52.0kg, with how much force does the rin ...continues

Problem 7.56

Please do not include your response in a .pdf format if at all possible, but Word documents are okay. Thanks! Here's the question: A 2.0 kg ball swings in a vertical circle on the end of an 80-cm-long string. The tension in the string is 20 N when its angle from the highest point on the circle is theta = 30 degrees. (a) ...continues
