A 1400 kg car pulls a 560 kg trailer away from a stoplight with an acceleration of 1.85 m/s^2. There is no friction acting on the trailer. a) Draw a free body diagram of the trailer. b) What is the net force on the trailer? c) What force does the trailer exert on the car?

NOTES ASK YOUR TEACHER The drawing shows a 25.1-kg crate that is initially at rest. Note that the view is one looking down on the top of the crate. Two forces, F1 and F2, are applied to the crate, and it begins to move. The coefficient of kinetic friction between the crate and the floor is uK = 0.386. Determine the magnitude and direction (relative to the x axis) of the acceleration of the crate. magnitude 1.65 Xm/s2 direction 20.3 F1 55.0 54.0 N F Top view Additional Materials eBook abc 2,318 3? ?

Two objects of masses m1 and m2, with m1 greater than m2, are connected by a string and sit on a perfectly smooth horizontal surface. Mass m2 is to the right of mass m1. A horizontal force F, directed to the right, is applied to m2, accelerating the bodies to the right. Which statement correctly describes the magnitude of the tension force in the string connecting the two masses? a. The tension is less than F but greater than zero. b. The tension equals F. c. The tension equals zero. d. The tension is greater than F. e. An expression for the tension magnitude cannot be determined without more information.

A 40.5 kg parachutist is moving straight downward with a speed of 3.70 m/sA) If the parachutist comes to rest with constant acceleration over a distance of 0.745 m , what force does the ground exert on her?B) If the parachutist comes to rest over a shorter distance, is the force exerted by the ground greater than, less than, or the same as in part A?
