FBDs and Net Force For each of the following situations construct the appropriate FBD. Be sure to clearly indicate the relative size of the forces and label them appropriately. Include air friction when the speeds are relatively high. A car travelling down the road slams on the brakes and is slowing down. A picture is supported by 3 cables. The first cable acts vertically. The second cable acts at an angle of 40 degrees to the horizontal and pulls up and left. The third cable exerts a force at an angle of 15 degrees to the vertical and pulls up and right. A ball rolls is thrown straight upwards at 100 km/h. Draw the FBD once the ball is in the air moving upwards. A heavy crate is moved up an inclined plane pulled by a rope and pushed by a person. Assume that the person exerts their force parallel to the incline plane. Calculate the net force acting on each object using the method of vector components. 152 N [right] + 45 N [right 35o down] 15 N [North] + 12 N [SW] + 25 N [E 40o S] A chew toy is being pulled on by two pets. The first pet exerts a force of 55 N to the right. The second pet exerts a force of 75 N [Up 25o Left] Determine the additional force required to keep the object at rest. Consider this problem as if viewed from overhead. The normal force and force of gravity will be directed out of the page and into the page respectively and will cancel each other out
