Question

1a . A constant force of 32.3 N pulls on a 20 kg block on a horizontal surface. The force is directed at 30^o above the horizontal. A friction force impedes the motion. If at the start of the motion the block was at rest and after 11 meters it has a velocity of 3, what is the coefficient of friction?

1b. What is the work done by the constant force when the block is moved 8 meters?

2.What constant, horizontal force must be applied to a 1,851 Kg car traveling on a horizontal road at 33 km/h to stop it in 31 meters?

3a. A horizontal constant force of 9.2 N is applied to a 9.3 Kg block which moves on a frictionless table. The block is initially at rest and after moving some distance it has a velocity of 11.6 m/s. What is the final kinetic energy of the block?

3b. What is the distance moved?

Hey Buddy, Due to some time restrictions I am not able to solve all the questions at once. So kindly post the remaining questions as a single question to get it solved.

hope you will understand.

Thanks and Good luck!
