While standing on a bridge 14.1 m above the ground, you drop a stone from rest. When the stone has fallen 3.30 m, you throw a second stone straight down. What initial velocity must you give the second stone if they are both to reach the ground at the same instant? Take the downward direction to be the negative direction.

answer; equivalent to a one(1) horsepower motor;

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

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
