You are on a school bus driving north at 20 m/s. you walk toward the back of the bus with a velocity of 6 m/s. what is your velocity relative to the road?

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2

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

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain
