A 1300kg car pulls a 540kg trailer away from a stop light with an acceleration of 1.92 m/s2
a. What is the net force exerted by the car on the trailer in N?
b. What is the magnitude of the force that the trailer exerts on the car in N?
(c) What is the net force acting on the car in N?
A force of magnitude 8.11 N pushes 3 boxes with masses m1 = 1.30 kg, m2 = 3.20kg, and m3 = 4.90kg. Find the contact force between boxes 1 & 2, and between boxes 2 & 3.
Two crewmen pull a boat through a lock. One crewman pulls with a force of 130 N at an angle, θ = 35°, relative to the forward direction of the boat. The 2nd crewman, on the opp side of the lock, pulls at an angle of 45° degrees relative to the forward direction. With what force should the second crewman pull so that the net force of the two crewmen is in the forward direction?
A train is traveling up a 3.2 degree incline at 3.74 m/s when the last car breaks free starts to coast. How long does it take for the last car to come to rest?
