Question

a boy wants to hold a 50 kg box at rest on a snow covered hill. the hill makes an angle 30 degree with the horizontal what force the boy mast exert parallel To the slope

Answer 1

We know that the formula for force is

                                     F = mass x acceleration

Here the acceleration is caused by the force of gravity “g” whose value is 9.8 $m/s^2$

Since, angle of elevation is given, the formula is,

                                       F = mg sin(A)

Here A = 30°, substituting all the values,

                                       F = 50 x 9.8 x sin (30)

                                       Sin 30 = ½

                            F = 490 x 1/2 = 490/2 = 245 Newton
