WebYou actually don’t need the mass to solve for speed. For example, we can leave T in terms of mass (m), so that T = m*9.8 / cos30. Then, plugging this T into the derived equation for v [v = sqroot (Tsin30*Lsin30) / m], you get v = sqroot (m*9.8*sin30*Lsin30 / m*cos30). There is an m in the numerator and the m in the denominator, so they cancel. WebSine of 30 degrees, in case you haven't memorized it, sine of 30 degrees is 1/2. So T1 times 1/2 is equal to 100 Newtons. Divide both sides by 1/2 and you get T1 is equal to 200 Newtons. So now we've got to figure out what …

WebMar 24, 2024 · To calculate the mass of an object, use the formula d=m/v, where d is density, m is mass, and v is volume. So, if the density of the … WebAn object of mass m 1 = 5. 0 0 k g placed on a frictionless, horizontal table is connected to a string that passes over a pulley and then is fastened to a hanging object of mass m 2 = 9. 0 0 k g as shown in above figure.

WebJust take the block. Component all forces in x and y direction. Now equate the forces from up to down and the right to left. That should help. The equations you get will be used to find out mass of block. Also is there acceleration or block is in equilibrium? The object is in equilibrium, so it's not accelerating. WebNov 26, 2016 · An object with mass m1 = 5.00 kg, rests on a frictionless horizontal table and is connected to a cable that passes over a pulley and is then fastened to a hanging object with mass m2 = 9.0 kg, as shown in Figure P4.30. Find the acceleration of each object and the tension in the cable. WebThe student attaches the free end of the string to the ceiling and pulls the object-string system so that the string makes an angle of 5 degrees from the object's vertical hanging position. The student then releases the object from rest and uses a stopwatch to measure the time it takes for the object to make one complete oscillation. gaslight tv show julia roberts
