1) A man measures the acceleration of an elevator by using a spring balance. He fastens the scale to the roof, and suspends a mass from it. The scale reads 96.1 N when the elevator is at rest, and 98.2 N when the elevator is moving. What is the acceleration of the elevator? 2) A 35.6 kg block on a level, frictionless table is connected to a 20.1 kg mass by a rope passing over a frictionless pulley. What will be the tension on the string when mass 20.1 kg is released? 3) If you were to place yourself with mass 77 kg between two objects, Object A with mass 64 kg and Object B with mass 28 kg, set 126 m apart from center to center. How far from the center of planet A should you place yourself to balance the net gravitational force of A and B to zero? 4) A 3.8 kg object is allowed to slide down a 69 incline which has a coefficient of friction of 0.34. What is the object's acceleration (in m/s^2)? 5) A car of mass 2.64 x 103 kg is being driven at 36.5 m/s. The driver sees a massive hole 239 m ahead. What is the minimum time that the car needs to stop in time? 6) A force of 65.0 N is required to pull a 9.00 kg block of aluminum up a 30.0 ramp at a constant velocity. Calculate the coefficient of kinetic friction between the aluminium and the ramp
