A 1 kg-body moves upwards across the vertical wall due to the force F=20 N applied at the angle a = 30 with vertical. Find the acceleration of the body if the coefficient of friction is k = 0.05
Homework Answers
here ,
let the acceleration is a
Normal force , N = 20 * sin(30) = 10 N
Now, Using second law of motion
20 * cos(30) - 0.05 * 10 - 1 * 10 = 1 * a
a = 6.82 m/s^2
the acceleration due to body is 6.82 m/s^2
