As a logging truck rounds a bend in the road, some logs come loose and begin to roll without slipping down the mountainside. the mountain slopes upward at 48.0 ∘ above the horizontal, and we can model the logs as solid uniform cylinders of mass 575 kg and diameter 1.20 m . find the acceleration of the logs as they roll down the mountain. what is the friction force on the rolling logs? is it kinetic or static?

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
