Question

Billy and Tommy are fighting over a 18kg physics textbook. Tommy pulls to the right with 111N; Billy pulls left with 402N. What is the acceleration of the textbook?

Round to the nearest whole number. Do not include decimals or negative signs in your answer only the magnitude.

Answer 1

Find the net force (F_net) of the system.

Then use the equation: F_net = m*a where m is the mass of the box and a is the acceleration of the box.
