Billie Budten and Mia Neezhirt are having an intense argument at the lunch table. They are adding two force vectors together to determine the resultant force. The magnitude of the two forces are 3 N and 4 N. Billie is arguing that the sum of the two forces is 7 N. Mia argues that the two forces add together to equal 5 N. Who is right? Explain.
The diagram below is a top-down view of two children pulling a 11.6-kg sled along the snow. The first child exerts a force of F1 = 10 N at an angle ?1 = 45° counterclockwise from the positive x direction. The second child exerts a force of F2 = 6 N at an angle ?2 = 30° clockwise from the positive x direction.
(A) Find the magnitude (in N) and direction of the friction force acting on the sled if it moves with constant velocity.
magnitude = ?
direction (counterclockwise from the +x-axis) = ?
(B) What is the coefficient of kinetic friction between the sled and the ground?
(C) What is the magnitude of the acceleration (in m/s2) of the sled if F1 is doubled and F2 is halved in magnitude?
