Plz help 1 : Give an example of motion in which acceleration of an object is against direction of motion
2 : Define uniform acceleration . What is the acceleration of body moving with uniform velocity ?
3 : How long will it take for a body accelerating by 2 m/s^2 to gain a velocity of 10 m/s starting from rest .

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.

Erosion of the beach is normally a slow process. however, in certain situations, large chunks of shore may wash out to sea. what could cause this to happen?

At time t=0, a particle is located at the point (3,6,9). it travels in a straight line to the point (5,2,7), has speed 8 at (3,6,9) and constant acceleration 2i−4j−2k. find an equation for the position vector of the particle.
