Question

An inclined plane make an angle of 30 degree with the horizontal. Find the contant force applied parallel to the plane required to caue a 15kg box to lide up the plane with anm acceleration of 1. 2m/^2 and down thge incline with an acceleration o1. 2m/^2. Neglect friction force

Answer 1

The constant force applied parallel to the plane required to cause a 15kg box to line up is 127.31 N.

Acceleration is the rate of change of the velocity of an item with appreciation to time. Accelerations are vector portions. The orientation of an item's acceleration is given by the orientation of the net pressure appearing on that object.

Calculation:-

mass =15 kg

Normal force = mgCos30°

parallel force = mgsin30°

acceleration required = 1.2 m/s²

Contact force = 15 × 9.8 × √3/2

                      = 127.31 N

Acceleration is the charge at which velocity modifications with time, in terms of each speed and route. A factor or an object moving in a straight line is accelerated if it quickens or slows down. Movement on a circle is extended despite the fact that the rate is consistent because the course is continually changing.
