- 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 2.1 cm from the elbow, how much force must the biceps exert to hold a 35 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 tutor told me that the answer to 1b was 10N but I don't understand why it would be 10N for the tension. If that is correct could someone break it down for me?If a system is balanced and not moving, the sum of the forces: O depends on the angle of gravity is up, in the y-direction is to the side, in the x-direction is zero
- When throwing a football you are always instructed to follow-through. What is the advantage of this? You are also instructed to stand with your feet about shoulder-width apart. What is the advantage of this?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 2.4 cm from the elbow, how much force must the biceps exert to hold a 42 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.of an object is the point at which the entire weight of the object may be considered concentrated * O Weight O Mass O center of gravity O Fulcrum
- You hang a mass of the right side of an equal arm balence and then pull on the hanger with your hand to keep it balanced. (a) if you pull on the left side of the balance do you have to pull up or down to keep the balance in equalibrium? b) if you pull on the right side of the balance do you have to pull up or down to keep the balance in equalibrium?A 1.5 kg block resting ina rough flat surface is pulled by a string. The string makes an angle of 20 degress with the horizontal. The coefficient of static friction between the blodk and the surface is 0.35.
