A 1.60 kilograms box is moving to the right with speed 8.50 meter per second on a horizontal, frictionless surface. At t = 0 a horizontal force is applied to the box. The force is directed to the left and has magnitude F(t) = (6.00 N/S2)t.
Find what distance does the box move from its position at t=0 before its speed is reduced to zero?
If the force continues to be applied, evaluate what is the speed of the box at 3.00?
The drawing shows a graph of two waves traveling to the right at the same speed. Using the data inthe drawing, determine the wavelength of each wave. The speed of the wavesis 19 m/s; calculate the frequency of each one.
