How much tension must a rope withstand if it is used to accelerate 20.5 kg crate horizontally along a frictionless surface of 2.50m/s^2How much tension must this rope withstand if it could be used to lift this crate?
volume 2^3 cubic centimeter 8 cc density 2.7 g/cc mass densityvolume 2.78 21.6 grams
C) 22 Grams is most correct 1st a 2cm x 2cm x 2cm cube is 8 cc's, 2.70 g/cc which the mass will be 21.6 grams2nd as you have to round to get to the answer you don't keep the significant digits in the answer21.6 - 22 grams
I might not be doing this right since its been like two weeks since I learned it and I don't have a calculator, but none of those answers are right, the equation is (8 cm cubed) times 2.70 (grams) and that is more then 16 but less then 22Also you have 22 on there twice.
density mass/volume Therefore, mass density x volume 2.7 x 2^3 (volume l^3 for cube) 21.6 grams which is close to 22 grams therefore your answer is A) 22.0 grams or C) 22 grams both are the same lol
Tension the rope must withstand for horizontal motion mass x acceleration T 20.5 x 2.5 51.25 N Tension the rope must withstand while lifting the crane m(a+g) If g 9.8m/s? Then T 20.5(9.8+2.5) 20.5 x 12.3 252.15 N Wasiq Khurshid
