A small object is placed at the top of an incline that is essentially frictionless. The object slides down the incline onto a rough horizontal surface, where it stops in 5.0 s after traveling 60 m. (a) What is the speed of the object at the bottom of the incline and its acceleration along the horizontal surface? (b) What is the height of the incline?
Solve it correctly please. I will rate with 2-3 ratings. But need correct answer.
The mass m is attached to a spring of free length b and stiffness k. The coefficient of friction
between the mass and the horizontal rod is u. The acceleration of the mass can be shown to be
x=-f(x), where
k
f(x) = ug+(b + x) 1–-
m
b² +x²
If the mass is released from rest at x = b, its speed at x = 0 is given by
1. Compute vo by numerical Simpson's 1/3 and 3/8 integration and compare between them
with different step size, using the data m = 0.9 kg. b = 0.6 m, =0.3, k = 100 N/m, and g
= 9.81 m/s.
2. Develop a MATLAB code to solve the equation for both methods.
3. Plot the acceleration of the mass versus x, and find the area under the curve by MATLAB
built-in function.
4. Can we find an exact solution??Try it.
