For the situation in part f, find the magnitude of the force f (in kg⋅m/s2) necessary to make the block move. View available hint(s) hint 1. Numerical solution opened hint you solved for an expression for f in the last part. What numbers must be plugged in to solve for a numerical answer?

i agree kid

explanation:

a

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
