Three blocks, each having a mass of 1.16 kg, are connected by rigid rods of negligible mass and are supported by a frictionless surface. Forces F1 and F2, of magnitude 5.30 N and 10.6 N respectively, are applied to the ends of the blocks as shown in the figure below. Find the forces acting on block B (the +x direction is to the right)
A) The magnitude of the force applied by the rod on the left:
B) The magnitude of the force applied by the rod on the right:
A square with ½-meter long sides has +1 nC at the top left corner, +2 nC at the bottom right corner, Calculate the components of the Electric field at the top left corner add each contribution separately
A cart mass M moves on a frictionless track. It is attached to a string, which goes over a pulley wheel & has a mass m hanging from it. At t=0 s the cart starts from rest & accelerates. Find the tension in the sting & acceleration of the cart.

How much work must be completed to accelerate a baton from rest to an angular speed of 7.79 rad/s about its center? Consider the baton to be a uniform rod of length 0.596m and mass 0.495kg.
The ball rebounds straight upward to a height of 0.700 m. Illustrate what are the magnitude and direction of the impulse of the net force applied to the ball during the collision with the floor?
A 110 granite cube slides down a 45 degree frictionless ramp. At the bottom, just as it exits onto a horizontal table, it collides with a 235 steel cube at rest. How high above the table should the granite cube be released to give the steel cube a..
Two spheres of mass m and a third sphere of mass M form an equilateral triangle, and a fourth sphere of mass mB is at center of the triangle.
How much work must this force do to stop the wheel. An electron moving along the x axis has a position given by x = 11te-1t m, where t is in seconds. How far is an electron from the origin when it momentarily stops.
A penny of mass 3.10 g rests on a small 22.40 g block supported by a spinning disk of radius 11 cm. The coefficients of friction between block and disk are 0.715 (static) and 0.64 (kinetic) while those for the penny and block are 0.564 (static) an..
