Aball is thrown downward from the top of a building that is 60 meters high. the initial velocity of theball is 30m/s, and the magnitude of the acceleration due to air resistance is 5v(wherevrepresentsvelocity). find an expression for the position of the particle at timet. also, determine the terminalvelocity (assume that gravity is 10m/s2).

Acar accelerates from 5.0 m/s to to 11 m/s at a rate of 3.0 m/s^2. how far does it travel while accelerating? 20m 117m 43m 16m

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.

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
