I would like some help for this question I asked someone before but their handwriting made it so that it was not eligible

1. A 20.0-kg block is pushed eastward from rest along a horizontal, frictionless surface with a horizontal force given by the graph below. [4 mark] a) How much work is done in moving the block the first 6.00 m? b) What is the block's kinetic energy after it has moved 8.00 m? c) What is its velocity at the 8.00 m mark? Force (N) 10 0 1 2 3 4 5 6 7 8 9 10 Distance (m)2. A spring bumper, with a force-compression relationship given by F = (40.0 Nimix, is compressed 3.00 cm. [4 mark] a] What elastic potential energy is stored in the spring at this compression? b) The spring is compressed further to 8.00 cm. What is the change in elastic potential energy? c} A 0.600kg cart is placed against the compressed spring in part b on a horizontal, frictionless plane. The system is released. With what speed does the cart leave the spring
