Joey drags his 25kg brother across the floor with a force of 12 N to the right at a constant velocity. Determine the normal force and the frictional force applied to the little brother. Draw the force diagram before solving the problem.

Since the velocity is constant, using Newton's First and Third Laws we know that the Friction and the Force are equal. So the friction is -12 Newtons.

Now the Normal Force (N) is also equal to the weight since the body is at a perfect balance.

So Weight is m*g = 25*10 = 250N

So N=250N

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
