A 85 kg person stands on a scale. a.) What would be the scale readout? |N=[ mg (Express in Newtons, and as a multiple of the person's weight.) Now, find a general expression for the scale readout, in terms of the person's mass, acceleration, and/or g. Show that it can be used to get the answer for part a above, and then use it to get the answers for all of the following parts: b.) If the person stands on the scale in an elevator accelerating upwards at 1 m/s², what is the scale readout? |N=[ .mg (Does the person feel heavier or lighter than the "usual" of part a?) c.) If the person stands on the scale in an elevator accelerating downwards at 1 m/s², what is the scale readout? mg (Does the person feel heavier or lighter than usual?) d.) If the person stands on the scale in an elevator accelerating downwards at 9.8 m/s2, what is the scale readout? N= mg (Does the person feel heavier or lighter than usual?) e.) In parts b-d, was the actual weight of the person different? Explain the…
The ramp in (Figure 1) is frictionless. Suppose that θ=45. If the blocks are released from rest, which way does the 10 kg block slide, and what is its acceleration? Enter a positive value if 10 kg block accelerates up the ramp, and a negative value otherwise. Express your answer with the appropriate units.
Two masses B and C are connected with a string passing over a friction less pully, assuming the coefficient of friction between the table and block is μ=0.4 , and the acceleration of gravity g=9.81 m/s2. Solve the following questions (show all the steps of your calculations): A. Draw the free body diagram of the two masses.B. Find an expression of the acceleration of the two masses in terms of ?? and ??.C. Determine the tension in the rope in terms of ?? and ??.D. If ??= ʎ kg, ?? = (ʎ-5) kg, determine the acceleration of two blocks and the tension in the rope.(ʎ= the final two numbers of your ID +10, and, gravitational acceleration, g = 9.81 m/s2).

Problem 1: A book is resting on a frictionless table until someone suddenly starts applying a constant force on it right until it reaches the end of the table. The book was constantly accelerating until it reached the end of the table. First, write down your thinking process as in the previous example, and then draw in the space provided below the book's motion diagram along with the velocity, acceleration, and force vectors. Draw book's motion diagram with velocity, acceleration, and force vectors. (Hint: Since the motion is horizontal, draw a horizontal motion diagram.)
problem 1. Consider a ball being tossed straight upwards as shown in the picture below. Indicate the direction of velocity and acceleration in the beginning, midpoint, and end of its motion. problem 2. Consider two balls being released from the same height at the same moment. One ball weigh 2 times more than the other one. Which one do you think will reach the ground first?
Bronco skydives and parachutes from a stationary helicopter. Various stages of fall are shown in positions a through f as illustrated below. Using Newton's 2nd law, a = F(net)/m = W - R , where a is acceleration, W is weight and R is air Resistance. Find Bronco's acceleration at each positions athrough f (Type in on Google form answers a-f, show supporting calculations on your notes). Bronco's mass is 100 kg so his weight W is a constant 1000 N. Air resistance R varies with speed and cross-sectional area as show.
Continue with pic Considering this, what impact would a half‑pound rock traveling at the calculated speed likely have on someone if it struck them in the forehead? A. The impact would likely cause serious injury. B. The impact would hurt a little but would likely not cause any injury. Suppose David missed. What distance dd would the rock travel before striking the ground if David released it from a height of H=4.95 ft?H=4.95 ft? Assume there is no air friction. Can someone help with this? I can't even understand the question. Thanks
