What is the momentum of a 3kg ball that is traveling at 5m/s

Debbie places two shopping carts in a cart corral she pushes the first cart which then pushes a second cart what force is being exerted

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.

Suppose a force of 60 n is required to stretch and hold a spring 0.1 m from its equilibrium position. a. assuming the spring obeys hooke's law, find the spring constant k. b. how much work is required to compress the spring 0.5 m from its equilibrium position? c. how much work is required to stretch the spring 0.6 m from its equilibrium position? d. how much additional work is required to stretch the spring 0.1 m if it has already been stretched 0.1 m from its equilibrium? a. kequals 600
