Please answer the following questions step by step for me to understand, I am having a tough time with physics. Thank you so much in advance.

Page 1 of 2 GP1: Homework for November 7th 2022 A 0.100-kg ball is thrown straight up into the air with an initial speed of 15.0 m/s. Find the momentum of the ball (a) at its maximum height and (b) halfway up to its maximum height. A 40.0-kg child standing on a frozen pond throws a 0.500-kg stone to the east with a speed of 5.00 m/s. Ne- glecting friction between child and ice, find the recoil velocity of the child. A pitcher claims he can throw a baseball with as much momentum as a 3.00-g bullet moving with a speed of 1 500 m/s. A baseball has a mass of 0.145 kg. What must be its speed if the pitcher's claim is valid? How fast can you set the Earth moving? In particular, when you jump straight up as high as you can, you give the Earth a maximum recoil speed of what order of magnitude? Model the Earth as a perfectly solid object. In your solution, state the physical quantities you take as data and the values you measure or estimate for them.Two blocks of masses Mand 3M are placed on a hori- zontal, frictionless surface. A light spring is attached to one of them, and the blocks are pushed together with the spring between them ( figure ). A cord initially holding the blocks together is burned; after this, the block of mass 3M moves to the right with a speed of 2.00 m/s. (a) What is the speed of the block of mass M? (b) Find the original elastic energy in the spring if M = 0.350 kg. M 3M Before 2.00 m/s 3M M After In a slow-pitch softball game, a 0.200-kg softball crossed the plate at 15.0 m/s at an angle of 45.0 below the hor- izontal. The ball was hit at 40.0 m/s, 30.0 above the horizontal. (a) Determine the impulse delivered to the ball. (b) If the force on the ball increased linearly for 4.00 ms, held constant for 20.0 ms, and then decreased to zero linearly in another 4.00 ms, what was the maxi- mum force on the ball
