Awave has a frequency of 100 hz and a wave speed of 4.0 m/s. what is the wavelength?

a. 25 m
b. 0.40 m
c. 0.04 m
d. 400 m

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.

The friction of the water on a boat produces an acceleration of -10. m/s2. if the boat is traveling at 30. m/s and the motor is shut off, how long it take the boat to slow down to 5.0 m/s?

Aforce is a vector quantity because it has both?
