Asmall, 0.10 kg cart is moving at 1.54 m/s when it collides with a larger 1.52 kg cart at rest. after the elastic collision, the small cart recoils (i. e. bounces off the larger cart and travels in the opposite direction) at a speed of 0.76 m/s.(a) what is the magnitude (absolute value) of the change in momentum for the small cart? kg m/s(b) what is the speed (absolute value of the velocity) of the larger cart after the collision? m/s
18 kilometers, in total!
the formula for acceleration is the velocity times the inverse of time so it would be 21 times 1/13. so roughly 0. is the acceleration(m/s^2).
why was my answer taken off? there is no way to show evidence for this but ig i can explain. the electrical energy is what is used to power the radio so it works, then the energy is used to catch radio waves which makes sound energy. so the answer is c, electrical energy to sound energy
