A hanging weight, with a mass of m, -0.370, is attached by a rope to a block with mass-0070 Ahow in the gure below. The rope goes over a pulley with a f.350 G. The pulley can be modeled as a hollow cylinder with an inner radius of R = 0.0200, and an outer radius of R, -0.0300 m the mass of the spoke is negligible. As the weight fals, the black shoes on the table, and the coefficient of...

A Review Motor M exerts a constant force of P = 720 N on the rope. (Figure 1) Part A If the 120-kg post is at rest when 0 = 0°, determine the angular velocity of the post at the instant 0 = 60 ° . Neglect the mass of the pulley and its size, and consider the post as a slender rod. Express your answer using three significant figures. Η ΑΣΦ vec ? W= rad/s Figure 1 of 1...
A particle P moves along a straight line in such a way that at time t seconds its velocity v m s^-1 is given by v = 1/2 t^2 - 3t + 4 Find the times when P is at rest. the total distance travelled by P between t = 0 and t = 4.
The 300 kg mine cart is hoisted up the incline using the cable
and motor, M. The force in the cable is F= (300t)N, where t is in
seconds. The initial velocity is 3 m/s at s=3 and t=0. Determine
the velocity when t=3 seconds. The angle of the incline is 35
degrees.
In the figure below, a motor winds in the cable with a constant acceleration, such that the 10-kg crate moves a distance s = 3 min 3 seconds, starting from rest. (vo = 0). The coefficient of kinetic friction between the crate and the plane is Mk = 0.3. M A 30° Determine the tension T developed in the cable.
p mv 6. A 0.5 kg blue dynamics cart is moving with an initial velocity of -2 m/s when it collides with a 0.25 kg red dynamics cart. The red cart is initially moving with a velocity of +4 m/s. As a result of the collision, the blue dynamics cart has a final velocity of +0.8 m/s. What is the final velocity of the red cart? 7. Starting from rest, a 1600 kg car is subject to a net force...
