- When you lift an object by moving only your forearm, the main lifting muscle in your arm is the biceps. Suppose the mass of a forearm with hand is 1.60 kg. If the biceps is connected to the forearm a distance of 2.2 cm from the elbow, how much force must the biceps exert to hold a 39 N ball at the end of the forearm at distance of 36.0 cm from the elbow, with the forearm parallel to the floor, in Newtons? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.A handtruck/dolly is being pulled up a board-ramp inclined 32° with dollyload combined weight of 296 pounds (operator of the dolly not included). It is known that the board has a maximum load carrying capacity of 242 pounds at its center (weakest point) when horizontal. Round answers to 4 decimal places. Forced pointing down are negative. W2 2 32 wi ngs |w = 296 lb a) What is the component of the weight of the dolly perpendicular to the ramp (w1)? pounds b) What is the component of the weight of the dolly parallel to the ramp (w2)? w2 = pounds c) Will the board/ramp break? d) What force is required to pull the dolly up the ramp?Two hockey players check an opponent into boards simultaneously. Player 1 hits from the left at an angle of 37 degrees to horizontal and a force of 400N. Player 2 hits from the left at an angle of 41 degrees to horizontal and a force of 600N. What is the magnitude and direction of total force applied to opposing player
