Joann has rubbed a balloon with wool to give it a charge of -1.0 x 10^-6 C. She then acquires a plastic golf tube with a charge of +4.0 x 10^-6 C localized at a given position. She holds the location of charge on the plastic golf tube a distance of 50.0 cm above the balloon. Determine the electrical force of attraction between the golf tube and the balloon

Aferris wheel is a vertical, circular amusement ride with radius 9 m. riders sit on seats that swivel to remain horizontal. the ferris wheel rotates at a constant rate, going around once in 9 s. consider a rider whose mass is 56 kg. at the bottom of the ride, what is the perpendicular component of the rate of change of the rider's momentum? at the bottom of the ride, what is the vector force exerted by the seat on the rider?

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative
