1. An unknown mass (mı) on a rough horizontal surface is attached by a wire that passes over a massless, frictionless pulley to a 2.50kg mass (m2) as shown below. The bottom of the hanging mass is 1.50m above the floor. The system is released from rest at t-0s and the 2.50kg mass strikes the floor 0.82s later. The system is now returned to its initial position and a 1.20kg mass is placed on top of the block of mass...

A small block of mass m slides along the frictionless loop the loop track shown below. If it starts from rest at point A, what is the speed of the block at point B? (v = squareroot (10 g R)) What is the net force acting on the block at point C? (Don't forget the gravitational force. (F = -mg (8i + j) At what height above the bottom should the block be released so that the normal force exerted...

Question 6.3
6.3 Consider a double mass-spring system with two masses of M and m on a frictionless surface, as shown in Figure 6.30. Mass m is connected to M by a spring of constant k and rest length lo. Mass M is connected to a fixed wall by a spring of constant k and rest length lo and a damper with constant b. Find the equations of motion of each mass. (HINT: See Tutorial 2.1.) risto M wa ww...

Assignment:-GCA-CH07A work-KE Theory Pg12 SCALE-UP Table: Station: A block of mass M is launched up a rough plane that makes an angle θ with the horizontal by placing (not attached) it against a massless spring compressed by a distance d and releasing it from rest (see "Initial stage" in the figure at right). The block slides a distance L (>d) up the plane and comes off the plane with an unknown speed v (see "Final stage" in the figure at...

1. A solid, uniform sphere with a mass of 2.0 kg is rolling from rest down an incline plane from the top of the plane. The incline plane makes an angle of 20° with the horizontal and has a height of 2.0 m. At the bottom of the incline plane, the surface levels out to a frictionless horizontal surface. A spring with a spring constant...
