# 2) Let's say you got a summer job as a dog walker. Each force below represents the magnitude of the force from each of the dogs. You are at the center of all the forces, which will be the origin for this problem. (A) Find the magnitude of the net force acting on you as a result of all the dogs pulling you in different directions (report answers to 3 sig figs, show basic starting equations, and each x and y component). (B) Find the angle the resultant vector makes from the positive x-axis (report answers to 3 sig figs and show basing staring equations). (C) If your mass was 70.0 kg, what would the magnitude of your acceleration be due to this net force (report answers to 3 sig figs and show basic starting equations)? B = 40 N 25° 35° 40° A = 30 N C = 50 N

Forces of 60 N at 170 degrees, and 40 N at an angle of 220 degrees, measured counter-clockwise from the positive x- axis, act on an object. What are the components (F1x, F1y) of the first force force (in Newtons)? Submit Answer Tries 0/2 What are the components (F2x, F2y) of the second force force (in Newtons)? Submit Answer Tries 0/2 What are the components (Fx, Fy) of the resultant force (in Newtons)? Submit Answer Tries 0/2 What is the magnitude of the resultant force (in Newtons)? Submit Answer Tries 0/2 What is the angle of the resultant force with respect to x-axis? (positive values only) Submit Answer Tries 0/2

A mother holds a baby's stroller stationary on a hill with a 20° incline. The stroller and baby weigh 200 N. Resolve the force into components that are parallel and perpendicular to the hill and state the magnitudes of the components. For the first blank state the PARALLEL component rounded to 2 decimal places. For the second blank state the PERPENDICULAR component to 2 decimal places. Blank # 1 Blank # 2 A A/

Krystal's cat, Charlie, had an unfortunate experience this morning. Charlie climbed the curtain and was afraid to come back down. Krystal heard the meowing and came to help him down. She decided this was a good opportunity to calculate the tension force Charlie exerted on the curtains. She placed him on a scale and used his mass to calculate the tension force on the curtains. If the cat caused 37N of tension on the curtain, what is Charlie's mass?

A skier is standing on a 30o hill.  Draw the hill and add idealized force vectors that represent the force of the skier (FS), the normal force (FN), and the force of friction (FF).

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?

A man pulls a cement block with a force of 450N using a rope that makes an angle of 35.0 degrees above the horizontal. What is the x-component of his pulling force?

What is the frictional force acting at A?  answer in N using 3 significant digits. What is the frictional force acting at B? answer in N using 3 significant digits.
