An object starts from rest and travels in a straight line with an acceleration of 5.0 $m/s^{2}$ for 4.0 seconds. I then reduces its acceleration to $2.7m/s^{2}$ for an additional 8.5 seconds. The magnitude of the velocity at the end of the 8.5 second interval is Your Answer: $\square $ $\square $ Answer units

A rocket is launched from the ground and travels in a straight path. The angle of inclination of the rocket's path is 1.35 radians (That is, the rocket's path and the ground form an angle measuring 1.35 radians.) a. What is the slope of the rocket's path? $\square $ b. If the rocket has traveled 55 yards horizontally since it was launched, how high is the rocket above the ground? $\square $ yards c. At some point in time the rocket is 405 yards above the ground. How far has the rocket traveled horizontally (since it was launched) at this point in time? $\square $ yards
