Calculating Final Velocity Try it
A roller coaster is traveling at 13 m/s when it approaches a hill that is 400 m long. Heading down the hill, it
accelerates at 4.0 m/s2. What is the final velocity of the roller coaster? Round your answer to the nearest whole
number
m/s

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
