Complete solutions need for all handwriting possible??

What Have I Learned So Far? Solve the following problems. Write your answers on a separate sheet of paper. Show your complete solutions. 1. A 7.0-kg crate is pushed upward to have an initial speed of 30.0 m/s directed upward along 30 m/s a frictionless inclined plane. Find the horizontal and vertical components of the highest position 7.0 kg that the crate can reach. 30 2. The given figure shows an Atwood machine with two blocks that weigh 10.0 kg and 5.0 kg. These blocks are connected by a massless string that goes along a frictionless and massless pulley. Suppose a 10.0 kg spring has a force constant of 1 500 N/ m on a pit as shown in the figure. a. Using the law of conservation of energy, find the speed of the 10-kg block when it reaches the end of the spring if the system will be released from rest. b. What will be the maximum compression length of the spring when the heavier block hits it? 5.0 kgWhat Have I Learned So Far? Solve the following problems. Write your answers on a separate sheet of paper. Show your complete solutions. 1. Carlo pushes a 35-kg box on a floor level and displaces it 5 m from its initial position. a. If the force applied to the box is 500 N, what must be the magnitude and the direction of the frictional force on the surface? b. How much work is done by Carlo and by friction on the box? c. How much work is done on the box by the normal force and by gravity? d. What is the net work done on the box by all of the forces applied to it? 2. Why do you think is it more difficult to climb up the stairs than to go down on it? Explain your answer using the concepts of work and force
