In the open ocean, the distance between wave
crests is 50 meters and the wave oscillates up and
down 0.16 times a second. This causes the wave
to pass a given point every 6.25 seconds.
What is the speed of this wave?
A 1.0 m/s
c. 39.1 m/s
B. 8.0 m/s
D. 312.5 m/s

The graph below represents the work done by a student while running up flights of stairs. determine the student's power output after 10 seconds: 1600 j/s 8000 j/s 160 j/s 800 j/s

20. threshold braking in the vehicle's braking system occurs when a. the brake pedal is pushed, heel on floorboard, with full foot pressure. b. the brakes are exerting full braking power, without traction loss. c. the driver begins pushing down the brake pedal, with moderate slowdown. d. the brakes just begin to take hold with a gradual slowdown.

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.
