Question
can anyone solve these quation for me plz
A crankshaft with a diameter of 3.0 cm, rotating at 2600 rpm comes to a halt in 1.80 s. How ma * revolutions does the crankshaft make as it stops? 54 13 18 39 shown in the figure. A traffic light weighing 10.2 kg is supported by two ropes as shown in the figure. The tensions in the ropes are closest to: 83 N 63 N 56 N 66 N An experiment aims to determine the influence of location on weight by placing persons of same mass, 72 kg, on identical scales at the North Pole as well as the Equator. The Earth will be considered a perfect sphere of radius 6.37 106 m, with a rotation period of 24 hours. Calculate the centripetal acceleration of a point at the Equator. Without calculation, give a value for that same acceleration at the North Pole, justifying your answer. Draw a free body diagram of a person standing on a scale, representing all external forces, as well as centripetal acceleration in relation to the standard vertical axis y. Use Newton's second law to calculate the person's weight at the North Pole and the Equator (use three significant figures) Conclude by what percentage the weight at the Equator differs from the one at the North Pole. Is the following statement reasonably accurate: "The weight matches the force due to gravity, when the object is at rest on a level scale"?Explanation / Answer

v = u - at
2600/60 = at
a = 24.07
S = ut -1/2at^2 = 2600/60 * 1.8 - 1/2 * 24 * 1.8^2 = 39
10) 2T sin(37) = mg
T = 83
