1. An object of mass m = 17 kg experiences 2 forces, FA and FB. Those two forces are perpendicular, their magnitudes are given as FA = 36N and FB = 77N. a) Redraw the figure on your workbook with appropriate scale.

b) Draw the resultant force.

c) Calculate the magnitude of the resultant force using the Pythagorean theorem.

d) Calculate the angle between the resultant force and FB, using arcsin or arccos or arctan (those functions are usually written as sin-1, cos-1, and tan-1 on CASIO scientific calculators).

e) Calculate the acceleration of the object using Newton's second law.

I'm kinda lost ! 1. when marilyn takes her pet dog for a walk, the dog walks at a veryconsistent pace of 0.55 m/s. draw a position-time graph to representmarilyn's dog walking the 19.8 m distance from the front of her house tothe nearest fire hydrant.2. both car a and car bleave school when a stopwatch reads zero. car atravels at a constant 75 km/h, and car b travels at a constant 85 km/h.a) draw a position-time graph showing the motion of both cars. howfar are the two cars from school when the stopwatch reads 2 hrs? calculate the distances and show them on your graph.b) both cars passed a gas station 120 km from the school. when dideach car pass the gas station? calculate the times and show themon your graph.3. the figure below shows the position-time graph showing a shopper'smovement up and down the aisle at a store.a) write a story describing the shopper's movements at the store.b) when does the shopper have a position of 6 m? c) how much time passes between when the shopper enters the aisleand when he gets to a position of 12 m? what is the shopper's averagevelocity between 37 s and 46 s?
