Answer #1

1. Weigh the block, equate the weight to mg; where g = 9.81 m/s2. Then,

Find the angle between the incline and the horizontal surface the incline is kept on, now weight is given by mgsin.

2. Force F on the mass m connected with the spring, is given by:

F = -kFn

Where Fn is the normal force on the mass, i.e. the weight of the mass, w = mg where g is acceleration due to gravity, 9.81 m/s2

1) A block is released from point A and it slides down an incline (theta = 30 degrees) where the coefficient of kinetic friction is 0.3. It goes 5m and hits a spring with a spring constant k = 500 N/m. While it is being acted upon by the spring, assume it is on a frictionless surface. a) How far is the spring compressed? b) How far does the block go up the plane on the rebound from the spring?...

A block with mass m1 = 8.8 kg is on an incline with an angle θ = 27° with respect to the horizontal. For the first question there is no friction between the incline and the block. 1. When there is no friction, what is the magnitude of the acceleration of the block? 2. Now with friction, the acceleration is measured to be only a = 3.52 m/s2. What is the coefficient of kinetic friction between the incline and the...

(1.) Sample Lab-Based Question... In the physics laboratory you are given a metal block that is approximately the size of a brick. You are also given 2.0m long wood plank with a pulley* attached to the end of it. Your objective is to experimentally determine the coefficient of kinetic friction ( μ k ), between the metal block and wood plank. *Note: you do not necessarilly need to use the pulley. (a.) From the list below, select the additional equipment...

1) a) A block of mass m slides down an inclined plane starting from rest. If the surface is inclined an angle theta above the horizontal, and the block reaches a speed V after covering a distance D along the incline, what is the coefficient of kinetic friction? b) at a distance D1 (still on the incline), the block comes to an instantaneous standstill against a spring with spring constant k. How far back up does the block? Why do...

A block of 1 kg, initially launched with a speed of 4 m/s rolls across a horizontal table surface over a distance of 3 m before coming to a stop, due to friction. I am not specifying μk, but I am telling you that μs < 1. Next the block is attached to a horizontal, unstretched spring of spring force constant k = 10 N/m, and given the same launching speed, on the same (horizontal) table surface. The other end...

As you know, a common example of a harmonic oscillator is a mass attached to a spring. In this problem, we will consider a horizontally moving block attached to a spring. Note that, since the gravitational potential energy is not changing in this case, it can be excluded from the calculations. For such a system, the potential energy is stored in the spring and is given by U=12kx2, where k is the force constant of the spring and x is...

1. Describe a situation where the block moves as the force is applied to it, yet the force does no work over a non-zero time interval. How can this be? 2. Set the initial position of the block to zero, and set the initial velocity to —3 m/s. Run the simulation. When is the work negative? When is it positive? Why? 3. Since the force is constant, what can you say about the acceleration of the block? 4. How can...
