An object is constrained by a cord to move in a circular path of radius 1.3-m on a frictionless, horizontal surface. The cord will break if the tension exceeds 15.7-N. The maximum kinetic energy that this object can have is J. Round your answer to the nearest whole number.

Aweight lifter raises a 1600 n barbell to a height of 2.0 meters. how much work was done? w = fd a) 30 joules b) 3000 joules c) 320 joules d) 3200 joules

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )

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.
