To push a 5-kg crate up a frictionless incline angled at 40° to the horizontal, a worker exerts a force of 150 N parallel to the incline. The crate moves a distance of 10 m, (use g = 10 m/s2). 1. What work is done on the crate by the worker? (In Joules)
2. What work is done on the crate by gravity? (Joules)
3. What is the work done on the crate due to the normal force of the inclined plane surface? (Joules)
4. What is the net work done on the crate? (Joules)
5. If the crate begins at rest, what is the final speed of the crate as it is moved from the bottom to the top of the inclined plane? (m/s)

An alligator swims to the left with a constant velocity of 5 \,\dfrac{\text{m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction. when the alligator sees a bird straight ahead, the alligator speeds up with a constant acceleration of 3 \,\dfrac{\text {m}}{\text s^2}3 s 2 m ? 3, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction leftward until it reaches a final velocity of 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction leftward. how many seconds does it take the alligator to speed up from 5 \,\dfrac{\text {m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction to 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction?
