in a physics lab, cate and shannon apply a 34.5 n rightward force to a 4.52-kg cart to accelerate it across a horizontal surface at a rate of 1.28 m/s/s. determine the friction force acting upon the cart.

Making a free-body diagram in which you display each unique force operating on the book is the first step in solving any problem like this. Gravity and normal force are the two vertical forces. Friction and the applied force are the two horizontal forces.

Since there is no vertical acceleration, gravity is the only force that exists. The equation can be used to determine each of these forces. Fgrav = m, G = 4.52 kg, 9.8 m/s/s, and N = 44.296

The sled's mass and acceleration can be used to calculate the net force. Fnet is equal to m * a * (4.52 kg * 1.28 m/s/s) * 5.7856 N, correctly.

The applied force must be greater than the friction force since the net force is to the right (in the direction of the applied force). Understanding net force as the vector sum of all the forces can help you calculate the friction force. 5.7856 N, right then equals 34.5 N, right plus friction.

Ffrict thus equals 28.7 N, left.

The cart is subject to a friction force of 28.7 N, left.
