- How large a net force is registered to accelerate a 1,824 kg SUV from rest to a speed of 28 m.s over a distance of 244m?For the cart in the picture. If its speed at point "a" is 15 m/s. What is the greatest speed reached by the trolley on the entire trajectory? Everything is done without friction.answer with worked out solution please!
- If your gravitational potential energy in your classroom located on the first floor is zero, on the second floor your gravitational potential energy is zero less than zero the same as the kinetic energy greater than zeroIndicate the one with more potential energy and explain why. A full plane or an empty plane (both are flying )?Potential energy depends on the distance between the two objects True False
