Please show me step by step how to answer the following questions, i am having a really tough time with physics. Thank you so much in advance.

GP1: Homework for October 31st 2022 A 0.600-kg particle has a speed of 2.00 m/s at point A and kinetic energy of 7.50 J at point B. What is (a) its ki- netic energy at A? (b) its speed at B? (c) the total work done on the particle as it moves from A to B? A 0.300-kg ball has a speed of 15.0 m/s. (a) What is its kinetic energy? (b) If its speed were doubled, what would be its kinetic energy? A 3.00-kg mass has an initial velocity vi = (6.00i - 2.00j) m/s. (a) What is its kinetic energy at this time? (b) Find the total work done on the object if its velocity changes to (8.00i + 4.00j) m/s. (Hint: Remember that 12 = v.v.) A bullet with a mass of 5.00 g and a speed of 600 m/s penetrates a tree to a depth of 4.00 cm. (a) Use work and energy considerations to find the average frictional force that stops the bullet. (b) Assuming that the fric- tional force is constant, determine how much time elapsed between the moment the bullet entered the tree and the moment it stopped. A picture tube in a certain television set is 36.0 cm long. The electrical force accelerates an electron in the tube from rest to 1.00% of the speed of light over this dis- tance. Determine (a) the kinetic energy of the electron as it strikes the screen at the end of the tube, (b) the magnitude of the average electrical force acting on the electron over this distance, (c) the magnitude of the av- erage acceleration of the electron over this distance, and (d) the time of flight.A block having a mass of 0.80 kg is given an initial velocity UA = 1.2 m/s to the right and collides with a spring of negli- gible mass and force constant k = 50 N/m, as shown in Fig- ure . Assuming the surface to be frictionless, calculate the maximum compression of the spring after the collision. x=0 VA A A particle of mass 0.500 kg is shot from Pas shown in Figure. The particle has an initial velocity v; with a horizontal component of 30.0 m/s. The particle rises to a maximum height of 20.0 m above P. Using the law of conservation of energy, determine (a) the vertical com- ponent of vi, (b) the work done by the gravitational force on the particle during its motion from Pto B, and (c) the horizontal and the vertical components of the velocity vector when the particle reaches B.
