Jake drags a sled of mass 18 kg across the snow. the sled is attached to a rope that he pulls with a force of 70 n at an angle of 40°. if there is no friction, what is the normal force acting on the sled?

The normal force acting on the sled 131.4048 Newtons.

Explanation:

On breaking up force of 70 N into vertical and horizontal components:

Vertical components:

Horizontal components:

The normal force is force acting perpendicular on an object.It is a balanced force.

The normal force acting on the sled 131.4048 Newtons.

the assestment will probley apele with cause and effect

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.
