A 712 kg car is traveling at 5.6 m/s when a force acts on it for 8.4s, changing its velocity to 10.2 m/s. What is the change in kinetic energy?

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

What is the temperature in degrees celsius of a substance with a tempature of 49k

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination.at the turning point, how far is the second student from the destination?
