From: 2004Meyers, Audrey Sent: Tuesday, September 05, 2000 7:37 PM To: 2004Myers, Peter Subject: RE: 1. There is a 15 kg block resting on a flat surface which is connected to a 40kg resting on a 50 degree incline. The coefficent of friction on the flat surface is 0.6, the coefficent on the incline is 0.3. the blocks are connected by a string which goes over a frictionless pully. Find the acceleration of the system and the tension in the chord. 2. A 7kg block is resting on a flat surface. A 90N force pushes the block at a 30 degree incline going down 15 m to the right. The coefficient of kinetic friction is 0.35 find: a. the normal force acting on the block b. the acceleration of the block c. the work done by friction 3. define a. newton's third law b. inertia c. non-inertial reference frame d. A car is moving around a curve of radius 450ft at a speed of 75 ft/s. What is the minimum value of the coefficent of static friction on the tires needed to keep it from skidding? e. If there was no friction on the tires on the car above, at what angle must the road be
