Yes; the acceleration of gravity is constant, so the speed increases with time.

Because it is gathering momentum as it travels on an angle. The gravity of earth acts on the cart, pullling it towards the center, all the while the weight of the cart is accelerated making the momentum!

Yes, due to the cart gaining momentum as it progresses down the inclination, an effect caused by its weight and gravitational force.

a million. (a) via fact the autos initiate at relax at a top "h" they have means potential "U." on the backside of the song at 0 top with regard to their beginning factor, all of that means potential has converted to kinetic potential "ok." U = mgh ok = m/2*v^2 2gh = v^2 for that reason to enhance v to 3v, you're able to enhance h to 9h. In different words, a element of 9. (b) No, the song is frictionless, so whether it curves sideways a similar rules nevertheless stick to. 2. The cart on the 2d ramp, via fact the cart would be going swifter earlier it hits the incline bump.

It does due to acceleration due to gravity which acts at 32 ft/sec sq. no matter what the weight.
