A husband and wife take turns pulling their child in a wagon along a horizontal sidewalk....

A husband and wife take turns pulling their child in a wagon along a horizontal sidewalk. Each exerts a constant force and pulls the wagon through the same displacement. They do the same amount of work, but the husband's pulling force is directed 58° above the horizontal, and the wife's pulling force is directed 38° above the horizontal. The husband pulls with a force whose magnitude is 71 N. What is the magnitude of the pulling force exerted by his...

A fan exerts a force of 10 N on a frictionless cart of mass 250 g,...

A fan exerts a force of 10 N on a frictionless cart of mass 250 g, accelerating the cart from rest over a distance of 0.5 m. The same fan is then used to accelerate a 500 g cart from rest over the same distance. Select ALL statements below that are TRUE about this situation: A) The energy transferred to both carts is different. B) The work done by the fan in both cases is the same. C) The final...

What is the force that the fist exerts on the top of the bottle?

A glass soda bottle is emptied of soda and filled to the very top with water. A cork is carefully fitted into the top of the bottle, leaving no air between the cork and the water. The top of the bottle has a diameter of D_top = 2.00 cm and the bottom of the bottle has a diameter of D_bot = 6.50 cm. The glass breaks when it is exposed to p_max = 70.0 MPa of pressure. A student hits...
