Question

A 0.5 kg mass is pulled across horizontal surface with friction by a string attached to a 0.10kg hanging mass. The acceleration is 1.25 m/s^2. Find the size of the frictional force on the block 0 98 N 0.75 0.355 N 0.23 N there is no way to find friction without the coefficient of friction A block starts from rest and slides down an inclined plane 1.2 meters long that is at an angle of 5 degrees. The coefficient of sliding friction is 0.05. what is the acceleration of the block down the plane due to gravity? 9.76 m/s^2 0.85 m/s^2 0.37 m/s^2 1.34 m/s'^2c) 0.49 m/s^2 A car with a mass of 1000 kg moving at 21 m/s come to a stop in a distance of 3 meters in a collision with a crash barrier. What is the average force on the car by the crash barrier? 73500 N 220500 N 7000 N 21000N there is no way to tell without knowing the time of the collision A block on a frictionless surface starts at a height of 2 meters above the floor and slides down a ramp 6 meters long.
