A shopper at the Fries’ market place pushes a 13.0-kg shopping cart at a constant velocity for a distance of 58.7 m on a level surface. He pushes in a direction 24.50 below the horizontal. A 53.8 N frictional force opposes the motion of the cart.

What is the magnitude of the force that the shopper exerts on the cart?

What type of light does this light bulb produce most (i. e. at what wavelength does the spectrum have maximum intensity)?
