PHYSICS 30 MOMENTUM AND IMPULSE Q9 ASSIGNMENT A. MOMENTUM AND IMPULSE a. C. 1. Use the concept of Impulse to describe one advantage of seatbelts. 2. A 5.00 kg mass is moving with a velocity of 3.50 m/s. A force of 4.00 N acts on the object increasing its velocity (in the same direction) to 12.5 m/s. Determine Change in momentum b. Impulse the mass experiences Time interval that the force was applied for 3. A 15.0 kg object is...
2. Two steel balls are colliding elastically. Ball 1 has a mass of 1.20 kg and is moving 3.00 m/s at an angle of 45 degrees measured from the positive X-axis before the collision. Ball 2 has a mass of 1.50 kg and is moving 2.50 m/s at an angle of 60 degrees above the negative X- axis before the collision. Assume the balls hit squarely without a glancing blow so the balls can roll in the direction calculated normally....
Problem 4 In a lab experiment, a cart of mass 2 kg, moving initially to the right at 3 m/s, collides head-on with a cart of unknown mass, moving initially to the left at 2 m/s. As a result of the collision, the carts bounce back with exactly the opposite velocity of what they had going in. Assume the system is effectively isolated (a)What is the mass of the second cart? (b)What is the total momentum of the system? (c)What...

Question 1 10 pts 1) A mass of 4 kg is moving at some velocity and collides inelastically with a 7 kg moving in the-x direction at 10 m/s. After the collision, both masses are moving in the -x direction and the total kinetic energy of both masses is 68 Joules. What was the momentum of the 4 kg mass before collision in kg m/s? Include a negative sign if moving in the negativex direction.
