In the figure below, the current in the long, straight wire is I1 = 19.8 A and the wire lies in the plane of the rectangle loop, which carries a current of I2 = 10 A . The dimensions in the figure are c = 0.1 m, a = 0.15 m, and , l = 0.45 m. Find the magnitude of the net force exerted on the loop by the magnetic field created by the wire.

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u.s. legal proceeding.)

Achild throws a ball with an initial speed of 8.00 m/s at an angle of 40.0° above the horizontal. the ball leaves her hand 1.00 m above the ground. how long is the ball in flight before it hits the ground?
