4. When a solid object is suspended from a spring scale in air the scale reads 21.7N. The object is then completely submerged in water and the spring scale reads 16.6N. Draw a free-body diagram for the object suspended from the scale in air. You may ignore the very small buoyant force from the air. Using a Newton's 2 nd law equation for the vertical direction on your FBD determine the mass of the object. Draw a free-body diagram for...

The figure gives the acceleration of a 4.0 kg particle as an applied force moves it from rest along an x axis from x = 0 to x = 9.0 m. The scale of the figure's vertical axis is set by a_s = 10.0 m/s^2. How much work has the force done on the particle when the particle reaches (a) x = 4.0 m, (b) x = 7.0 m, and (c) x = 9.0 m? What is the particle's speed...
The particle has a known mass m and is confined to move along the smooth horizontal slot
Given: The particle has a known mass m and is confined to move along the smooth horizontal slot due to the rotation of the rod OA. Also, the rod is rotating with a known constant angular velocity of θ. Assuming the particle contacts only one side of the slot at any instant, Find: a) The radial (vr) and transverse components (vθ) of the particle's velocity at the given instant. b) The radial (ar) and transverse components (aθ) of the particle's acceleration at the given...

A box with mass m = 1.2kg on an inclined frictionless surface is released from rest from a height h = 1.75 m. After reaching the bottom of the incline the box slides with friction (uk = 0.25) along a horizontal surface until coming to a rest after a distance d. 1. Draw a free body diagram for the box while it is on the incline. Clearly label all forces with standard names. 2. Draw a free body diagram for...
