1. A 1500 g object is being pushed by an applied force and accelerates at 4.08 m/se. What is the force applied if a frictional force is 62.5 N is acting on opposite direction?
Answer the following and show the Illustraion each problem
1. A 1500 g object is being pushed by an applied force and accelerates at 4.08 m/se. What is the force applied if a frictional force is 62.5 N is acting on opposite direction? 2. 2. A 2500 kg truck contains 130 cavans of rice, each with a mass of 50 kg. It is moving at a speed of 5 m/s. How many cavans of rice must be unloaded at a nearby grocery so that the truck can move 9 m/s at yet maintain the same momentum?
2. A 4.6 kg block resting on a smooth horizontal surface is attached to a string that passes over a frictionless pulley as shown in the figure. The pulley has a radius of .48 m. a force of 8.5 N pulls the other end of the string. As a result, the block moves a distance of .35m starting form rest. Find the following: a. Acceleration of the block b.
