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.

Um vetor representa um deslocamento cujo módulo é 20 m. se v faz um ângulo de 60 graus com a horizontal, qual é o valor das componentes horizontal e vertical deste vetor?

1.in one challenge on the titan games, competitors have to lift 200 pounds up a long ramp. angel is able to move the weight in 42 seconds. anthony gets it done in only 38 seconds. which statement is true? angel has more power than anthony. angel does more work than anthony. anthony does more work than angel. anthony has more power than angel. 2.a mountain climber exerts 41,000 j of work to climb a cliff. how much power does the climber need if she wants to finish in only 500 seconds? power = work / time 20,500,000 watts 82 watts 0.0122 watts 41,500 watts 3.your family is moving to a new apartment. while lifting a box 83 joules of work is done to put the box on a truck, you exert an upward force of 75 n for 3 s. how much power is required to do this? (hint: you only need two of the 3 numbers given! ) power = work / time 249 watts 25 watts 2075 watts 27.7 watts
