A truck of mass 3 tonnes moves up an incline at a constant velocity 10m/s against a frictional force 200N . The incline is such that it rises 1 m for every 15m along the incline. Calculatethe power output of the truck engine.(g=10m/s)

If the spring constant k of a pogo stick is 3500 n m and the weight of the person on the pogo stick is 700 n, how much is the spring in the botom of the pogo stick compressed?

Heterogeneous mixture with larger particles that never settle is

During the apollo moon missions, astronauts were concerned about the effects of newton's third law of motion when: o a. they ejected waste water, because they were concerned that it would push them off course. o b. they reentered earth's atmosphere, because they were carrying heavy moon rocks. o c. they took off from earth, because a large force was required to generate large acceleration. o d. they detected incoming space debris, because the inertia of the debris could damage their ship.
