Please help show work . I really need this important Grade just need answers I got my answers but not sure if correct

1. When riding your bicycle one day, you notice a toddler standing in the street in the path of a speeding car, and clearly doesn't notice the toddler. Still on your bike, you ride in front of the car, grabbing the toddler in one hand, saving her from certain death. If the combined mass of you and the bicycle is 95 kg, the toddler has a mass of 20 kg, and you are initially traveling at 25 m/s, what is your final velocity after you have grabbed the toddler? Round your answer to the nearest tenth and include units . 2. A 150 g baseball is thrown toward home plate with a speed of 40.0 m/s. The batter hits the ball directly back at the pitcher with a speed of 50.0 m/s. If the bat is in contact with the ball for 6.0 x 10-3 s, what is the average force exerted on the ball during the collision? Round your answer to the nearest whole number and include units. 3.A 70 kg hockey player moving at 5 m/s collides with a 90 kg hockey player initially at rest. Which experiences a greater acceleration? a. It depends on the initial direction of the players b. They experience the same acceleration. c. The 90 kg hockey player d. The 70 kg hockey player 4. A ball of mass 0. 440 kg moving east with an initial velocity of 3.30 m/s collides elastically with a 0.220 kg ball initially at rest. If the first ball has a velocity of 1.1 m/s after the collision, what is the final velocity of the second ball? Round your answer to one decimal place and include units. 5. Two cars traveling on a road collide elastically as one approaches the other from behind. Car A has a mass of 1450 kg and car B has a mass of 1550 kg. If Car A approaches at 4.50 m/s and Car B is moving at 3.20 m/s, in the same direction, what is the speed of Car B after the collision if Car A has a speed of 3.20 m/s after the collision? Round your answer to one decimal place and include units. Enter the numerical value in Blank 1 and the units in Blank 2. (Possible units: m, m/s, kg*m/s, kg, N, s, NS) 6. What is the impulse needed to stop a 20.0 kg bowling ball moving at 5 m/s? Round your answer to the nearest whole number and include units. Enter the numerical value in Blank 1 and the units in Blank 2. (Possible units: m, m/s, kg*m/s, kg, N, s, NS) 7. Suppose two astronauts on a spacewalk are floating motionless in space, 3.0 m apart. Astronaut B tosses a 15.0 kg IMAX camera to astronaut A. The IMAX camera is traveling with a speed of 7.5 m/s. What is the resulting speed of astronaut A after catching the camera? Round your answer to one decimal place and include units. 8. A ball of mass 200 g is traveling at 10.0 m/s directly toward a second ball, initially at rest. After the collision, the first ball goes backwards and the second ball moves at a speed of 6.67 m/s. What is the mass of the second ball? Round your answer to one decimal place and include units. Enter the numerical value in Blank 1 and the units in Blank 2. (Possible units: m, m/s, kg*m/s, kg, N, s, Ns) 9.A 1.25 kg block of wood sits at the edge of a table 0.752 m above the floor. A 10.5 g bullet moving horizontally with a speed of 725 m/s hits the block and embeds itself within the block. How far from the edge of the table does the block and bullet land? Use momentum and then projectile motion, from Module 3, to solve this problem. Round your answer to one decimal place and include units. Enter the numerical value in Blank 1 and the units in Blank 2. (Possible units: m, m/s, kg*m/s, kg, N, s, NS) 10. A 200 kg bumper car moving at 4.0 m/s is subject to an impulse of 800 N.s in the direction of travel. What is the change in momentum of the bumper car? a. 1600 kg-m/s b. 800 kg.m/s c. 10 kg.m/s d. 40 kg.m/ s
