What is the approximate momentum of a car with a mass of 1200 kg and a velocity of 30 km/hr (8.33 m/s)? O 40.0 kg m/s AO 13.0 kg m/s O 1000 kg m/s O 5400 kg m/s

Three objects are moving along a straight line as shown in the figure. Taking the positive direction to be to the right, what is the total momentum of this system? 5.00 m/s 4.00 m/s 2.00 m/s 8.00 kg 15.0 kg 3.00 kg -14.0 kg · m/s 0.00 kg m/s +14.0 kg m/s O +106 kg m/s

The force on an object, m, is given by: F = 30t² where F is in Newton and t in seconds. Determine the change in momentum between t = 1.0 s to t = 3.0 s. 140 kg m/s 400 kg m/s 360 kg m/s 340 kg m/s

A child runs at 3.0 m/s and jumps onto a sled, initially at rest. If the child's mass is 40 kg, and the sled's mass is 20 kg, what is the speed the child and sled slide off together after the collision? O2.0 m/s O 0.5 m/s O 3.0 m/s O 1.0 m/s
