Problems: 1) An NFL caliber wide receiver can reach a top speed of 10.0 m/s in only 2.4 s. What is
their acceleration during this time? (Hint: top speed = final velocity and we can assume
they start from rest - initial velocity = 0 m/s.)

Most energy in an ecosystem comes originally from_

The crank oa rotates in the vertical plane with a constant clockwise angular velocity ω0 of 5.6 rad/s. for the position where oa is horizontal, calculate the force under the light roller b of the 10.6-kg slender bar ab.

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
