Part 2: Complete the following math problems by using the Law ofMomentum Conservation.Formulas:i. Momentum = (mass) *(velocity)ii. Impulse = (Applied force) * (time)  and Impulse = Change in Momentumiii. Applied Force = (Change in Momentum) / (time)iv. For multiple objects: Total Momentum of everything before interaction =Total Momentum of everything after 6. A car of mass 1100kg moves at 24 m/s. What is the braking force needed tobring the car to a halt in 2.0 seconds? (Use i and iii) 7. What is the force on a 0.025 kg egg from a bed sheet as the egg hits thesheet at 4.0 m/s and takes 0.2 seconds to stop? (Use i and iii)8. A 8.0 kg shell leaves a 2.0 x 103 kg cannon, at a speed of 4.0x 102 m/s. What is the recoil speed of the cannon? (Use i and iv)9. A 1.0 kg dart moving horizontally at 10.0 m/s makes impact and sticks toa piece of wood with a mass of 9.0 kg, which then slides across a friction freesurface. What is the speed of the wood and dart after the collision? (Use i andiv)10. A 10,000-kg train car coasting at 10 m/s collides with a 2000-kgautomobile coasting at 30 m/s in the opposite direction. If the stick togetherafter the impact how fast and in what direction will they be moving? (Use i andiv)
