answer and solve all the following questions ( handwritten solution only neatly and clean box final answer) thankyou!

II. Explain the given illustrations below using your knowledge on Impulse and Momentum. BEFORE AFTER VA= 8 mk VB= 1 m/s VA'= 4 mk VB= ? B MA= 2000 kg Me= 4000 kg CRUNCH MA= 2000 kg Me= 4000 kg MOMENTUM: An object having a mass of 12.34 Kg has its velocity change from 8.78 m/s east to 3.45 m/s east. Find the object's change in momentum. O A 13.56 Kg object has a momentum of 23.45 Kg-m/s towards the east. What is the objects speed in m/s? Impulse O A 24.56 N force is applied to a 34.66Kg object to change its velocity from 9.01 m/s to 3.03 m/s. What is the impulse experienced by object in Ns? O A girl in a sled, with a total mass of 55.89 Kg, slides down a verdant hill and reaches a velocity of 8.06 m/s at the base. If the slide can exert a constant force of 251.34 N. How fast will the sled stop? FATE MAV The Impulse The Change in Momentum What average breaking force is necessary to stop a 1234.56 kg car travelling with an initial velocity of 12.34 m/s for 56.78 seconds? How long would it take for an upward force of 123.91 N to increase the velocity of a 67.01 kg object from 76.80 m/s to 80.05 m/s
