A man pushes on a piano of mass 180 kg so that it slides at
Substituting the given values (m = 180 kg, g = 9.8 m/s², θ = 11°), we find F1 = 180 kg * 9.8 m/s² * sin(11°) = 337 N. The direction of this force is up the incline. Step 4/7 For part (b), the piano is moving up the incline with a constant velocity. Again, …

2023年9月8日 · VIDEO ANSWER: As part of an experiment on momentum, a billiard ball with mass 0 .180 KG travels 1 .5 meter distance in 0 .5 seconds. What is the momentum of the ball? Momentum is mass into velocity. Mass is 0 .180 and we know that velocity is equal
SOLVED: A scooter is moving with a velocity of 20 m/s when
Acceleration is the rate of change of velocity. It can be found using the formula: Force = mass * acceleration Rearranging the formula to find acceleration gives: Acceleration = Force / mass Substituting the given values: Acceleration = 500 N / 180 kg = 2.78 m/s² The acceleration is negative because the scooter is slowing down.
'The entire branch O A has a mass of 180 kg with mass center at G ...
Identify the given information - Mass of the branch (m) = 180 kg - Mass center at G Step 2/4 Find the weight of the branch - Weight (W) = mass × gravity - W = 180 kg × 9.81 m/s² - W = 1765.8 N Step 3/4 Determine the distance between point O and the mass center G - We need more information to determine this distance.

As shown in Fig. El0.20, a string is wrapped several times
As shown in Fig. El0.20, a string is wrapped several times around the rim of a small hoop with radius 0.0800 $\mathrm{m}$ and mass 0.180 $\mathrm{kg} .$ The free end of the string is pulled upward in just the right way so that the hoop does not move vertically as the string unwinds. (a) Find the tension in the string as the string unwinds.
