please WRITE all equations used and circle final answer. draw diagrams and use equations covered in work, energy, and momentum.

1.a 300 g ball moving to the right at 5.0 m/s collides head-on with a 300 g ball that is moving to the left at 3.0 m/s. If the collision is perfectly elastic, what are the speed and direction of each ball after the collision?(Apply elastic Collision equations)

2.a 1500 kg car accelerates from rest. Belowfigureshows the net force on the car (propulsion force minus any drag forces) as it travels fromx= 0 m tox= 200 m. What is the car's speed after traveling 150 m?(Apply work and energy equation, using calculus)
