e SI entum is kg x m/s. The momentum of an object is always positive. 10 pts Question 11 A2.9-kg cart moving to the right with a speed of 5.2 m/s has a head-on collision with a 5.2-kg cart that is initially moving to the left with a speed of 9.6 m/s. After the collision, the 2.9-kg cart is moving to the left with a speed of 3.7 m/s. What is the final velocity of the 5.2-kg cart? Equation: miui...
Object A has mass mA = 9 kg and initial momentum PA = < 15,-8,0 > kgm/s, just before it strikes object B, which has mass mg = 12 kg. Just before the collision object B has initial momentum 8,1 = < 4,7,0 > kg. m/s. Consider a system consisting of both objects A and B. What is the total initial momentum of this system, just before the collision? sysj = (19,-1,0) kg.m/s The forces that A and B exert...
A bumper car with mass m1 = 107 kg is moving to the right with a velocity of v1 = 4.6 m/s. A second bumper car with mass m2 = 98 kg is moving to the left with a velocity of v2 = -3.2 m/s. The two cars have an elastic collision. Assume the surface is frictionless. 1) What is the velocity of the center of mass of the system? m/s 2) What is the initial velocity of car 1...
Q1 A small object with a momentum of magnitude 2.71 kg m/s approaches head-on a large object at rest. The small object bounces straight back with a momentum of magnitude 6.19 kg m/s. What is the magnitude of the small object's momentum change in kg m/s? Q2 A force acts on a 4.708 kg mass as follows: the force starts at zero and rises to 60.334 N linearly in 2.24 seconds, it remains at 60.334 N for another 5.756 seconds,...
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...
for both questions Two objects with masses represented by m, and m2 are moving such that their combined total momentum has a magnitude of 17.7 kg. m/s and points in a direction 71.5° above the positive x-axis. Object my is moving in the x direction with a speed of V1 = 2.90 m/s and my is moving in the y direction with a speed of v2 = 3.07 m/s. Determine the mass of each object in kilograms. kg m2 -...
An object (A) of mass m A = 29.0 kg is moving in a direction that makes angle of 40° north of east with a speed v A = 5.10 m/s, while object (B) of mass m B = 17.5 kg is moving due north with a speed v B = 7.85 m/s. The two objects collide and stick together in a completely inelastic collision. Find the magnitude of the final velocity of the two-object system after the collision. An...
