(A) What minimum length of cable is needed?
(B) What is the sag, h, of the cable?
Long parallel wires separated by 7.5 cm carry 3.3 Amperes each in opposite directions. What magnetic force per length acts on the wires
What is the final speed of the crate after being pulled. On a very muddy football field, a 100 linebacker tackles an 80 halfback. Immediately before the collision, linebacker is slipping with a velocity of 8.5 north and the halfback is sliding with..
A car speeds past a stationary police officer while travelling 115km/h. The officer immediately begins pursuit at a constant acceleration of 10.20 km/h/s (note the mixed units), just as the driver passes the officer.
A 72 person stands on a uniform ladder 4.5 long, that weighs 75. The floor is rough; hence, it exerts both a normal force, and a frictional force, on the ladder. The wall, on the other hand, is frictionless; it exerts only a normal force.
A tennis player receives a shot with the ball of mass 0.060kg travelling horizontally at v=43 m/s and returns the shot with the ball travelling horizontally at 60.00 m/s in the opposite direction.
