1) A block of mass 5.0 kg is on an incline that makes an angle of 45 degrees with the horizontal. The coefficient of kinetic between the block and the incline is 0.20. A string pulls on the block. The string runs parallel to the incline, then over a (Approximately frictionless and inertia free) wheel at the end of the incline, then down to an otherwise free hanging triangular object of mass 100 kg. What is the magnitude of the acceleration vector of the block in an inertial reference frame with origin fixed with respect to the tip of the incline? 2) A cannonball is fired off a 6 m high cliff with initial speed 9.9 ml's at an angle of 45 degrees above the horizontal and accelerates downward at 9.8 m!s*2. How far does the ball travel horizontally before it hits the ground
