Question

A block of mass 1.5 kg is placed on a frictionless inclined ramp of mass 16.4 kg, with the angle ?= 30o as shown below.

Calculate the size of the net horizontal force that must be applied to the ramp to prevent the block from accelerating with respect to the ramp?

A block of mass 1.5 kg is placed on a frictionless inclined ramp of mass 16.4 kg, with the angle ?= 30degree as shown below. Calculate the size of the net horizontal force that must be applied to the ramp to prevent the block from accelerating with respect to the ramp?

Explanation / Answer

total mass = 16.4 + 1.5 = 17.9 kgs


If fore F is applied over the system then both blocks will have same acceleration

and there will a n accleration of 2a on the wedge

so

we have following equation for the 1.5 kg block in equllibrium condition

g sin 30 = a cos30

a = g tan30

therefor the force should be


F=17.9 *9.81 *tan30

F = 101.38 N
