To find the normal force on the cart, we need to analyze the forces acting on it in the vertical direction.
The normal force is the force exerted by a surface to support the weight of an object resting on it. In this case, the normal force is equal to the downward force of gravity acting on the cart since the cart is not accelerating vertically.
The weight of the cart can be calculated using the formula weight = mass * gravitational acceleration. The mass of the cart is given as 7.32 kg, and the acceleration due to gravity is approximately 9.8 m/s^2.
weight = 7.32 kg * 9.8 m/s^2 = 71.736 N
Since the cart is not accelerating vertically, the normal force must be equal to the weight of the cart in the upward direction.
Therefore, the normal force on the cart is 71.736 N.
A shopper pushes a 7.32 kg grocery cart with a 14.7 N force directed at -32.7° below the horizontal.
