A A wire carrying 385 A to the motor of a commuter train feels an attractive force of 3.7 × 10*³ N/m due to a parallel wire carrying 4.5 A to a headlight. I = 385 A Iz = 4.5 A F = 3.7 × 10-3 N/m How far apart are the wires in meters?

At t = 0, a cart of mass m = 5 kg starts rolling down an incline, making an angle α = 20o with the horizontal. Initially the cart rolls down with no friction, but after traveling a distance of ∆ = 10 m it encounters a rough surface, where the coefficient of friction is k = 0.45. Find the acceleration of the cart along the incline (positive direction is downhill) after it encounters the rough surface.   A.9.8 m/s2  B.9.2 m/s2  C.7.7 m/s2  D.3.6 m/s2  E.3.4 m/s2  F.-0.8 m/s2

A rocket sled decelerates at a rate of a =197 m/s^2. Its passenger has a mass of 73.5 kg. a. Calculate the horizontal component of the force the seat exerts against his body. b. Compare his weight by using a ratio. The horizontal component of the forice is how many times his weight. Calculate the magniture and direction of the total force the seat exerts against his body.

Two packing crates of masses m, = 10.0 kg and m2 = 3.00 kg are connected by a light string that passes over a frictionless pulley as in the figure below. The 3.00 kg crate lies on a smooth incline of angle 42.0°. Find the acceleration of the 3.00 kg crate. m/s2 (up the incline) Find the tenslon in the string. N

Two blocks are joined by an inextensible cable as shown. If the system is released from rest, determine the velocity of block A after it has moved 2 m. Assume that the coefficient of kinetic friction between block A and the plane is 0.25 and that the pulley is weightdess and frictionless. 200 kg ㄱ 300 kg A B

g force is max gravetional force

A hockey puck (mass = 2 kg) leaves the players stick with a speed of 20 m/s and slides on the ice before coming to rest.The coefficient of friction between the puck and the ice is 0.9. How far will the puck slide after leaving the players stick? m
