Starting from rest ,a dog drags a 100.0 kg box for 3.00m as shown .the force diagram indicates the forces acting on the box. what is the work done by the dog?

Find the volume of the ellipsoid x^2+y^2+5z^2=36.

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

While goofing off at the ice skating rink, a student takes off her shoes and places each of them on the ice. her friend, a hockey player, then shoots a hockey puck at each shoe. the first puck immediately comes to rest after it collides with the left shoe. the second puck rebounds after it collides with the right shoe. if each hockey puck has the same incoming speed, which shoe has greater speed after the collision? the right shoe. both shoes have the same speed. the left shoe.
