A speedboat traveling at a constant velocity of 20 m/s passes a police boat at rest. The police boat decides that this is much too fast and starts his boat 8 seconds
after the speedboat passes. The police boat accelerates at 2.3 m/s2 for 10 s, then
travels at a constant velocity. When and where does the cop catch the speedboat?

Alarge box of mass m is pulled across a horizontal frictionless surface by a horizontal rope with tension t. a small box of mass m sits on top of the large box. the coefficients of static and

What organization and environment is described above?

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.
