A 0.50 kg mass is resting on a table. A student attaches a spring scale to the mass and pulls sideways with the 2.7 N force. In spite of this pull, the mass remains at rest.
- Draw a force diagram showing all the forces acting on half-kilogram in this situation.
- State the interaction (object) responsible for each force in the diagram.
- Calculate all the forces on the mass.

A 5 kilogram mass suspended from the end of a vertical spring stretches it by 1.225 metres. The system is placed in a medium offering a resistance (in Newtons) equal to 45 times the instantaneous velocity (in m/s). The mass is started in motion from the equilibrium position with an initial velocity of 1 m/s in the upward direction and with an applied external force F(t) 365 cos(3t) Newtons downwards. The displacement of the mass below the equilibrium position at...

1. (20 points) A block of mass 0.500 kg is forced against a spring of negligible mass, compressing the spring 0.200 m. as shown in the figure. When released from rest, the block leaves the spring after moving 0.200 m, then continues moving along the everywhere rough, horizontal tabletop. The force constant is 1.00 x 102N/m. The coefficient of kinetic friction between tabletop and block is 0.362. a) Draw a figure indicating and labeling all external forces acting on the...

Just question2(a) please. Thanks
2. An 10 kg object is hung from a spring attached to a fixed support. The spring constant of the spring is k = 40 N m-1. Suppose an external downward force of magnitude f(t) = 20e-2t N is applied to the object, and damping due to air resistance occurs with damping constant B = 40 N s m-1. Let y(t) denote the distance in metres of the object below its equilibrium position at time t...

Renee is on Spring Break and pulling her 21-kg suitcase through the airport at a constant speed of 0.47 m/s. She pulls on the strap with 120 N of force at an angle of 38° above the horizontal. Assume the ground to be flat, Draw a FBD showing the forces on the suitcase. Find the acceleration of the suitcase. Determine the normal force experienced by the suitcase. Determine the total resistive force (friction) experienced by the suitcase. Find the coefficient...

Given: F = mg where g = 9,8 N/kg (55 marks] 1. An experiment was done to see how the contact surface area affects the force of friction between a wooden block and a granite table. The contact surface area was changed by placing the block on its different sides. The force required to pull the block along at constant speed was measured with the spring-balance.
