A man riding upward in a freight elevator accidentally drops a package off the elevator when it is 100 ft from the ground. If the elevator maintains a constant upward speed of 4 ft/s, determine how high the elevator is from the ground the instant the package hits the ground. Draw the v–t curve for the package during the time it is in motion. Assume that the package was released with the same upward speed as the elevator.
A motorboat and its load weigh 980 kg. Assume that the propeller force is constant and equal to 24 kg, and the water resistance is numerically equal to 1.5v kg, where v is the speed at any instant time in m/sec. If the boat starts from rest, determine its speed at the end of 10 seconds.
Answer is 2.23 m/s
Packages having a mass of 4-kg are delivered from a conveyor to a ramp with a velocity of v = 0.8 m/s. What is the velocity in which the
packages will leave the ramp (at point B)? Consider e =30° andh = 12 m. The coefficient of the kinetic friction between the package and the ramp
is = 0.35
Note. Please write your final answer in m/s in the provided box. Report your answer in 2 decimal places. For example: 2.34 m/s
0.8 m/s
