- YOU are in an elevator moving at 14m / s * 2 and weight 71.4Kg your friend takes another elevator and they weights 100 kgbut feels the same force! How fast are they going?Two boxes of mass 30.0kg (on the left) and 10.0kg (on the right) are at rest side by side. You apply aforce of 310N on the leftmost box for 5.0s and they both slide across the floor. The larger boxexperiences a force of kinetic friction of 180N, and the boxes accelerate at a rate of 1.75 m/s2[R]. Calculate the force of friction on the rightmostbox.A body of mass m is retarded by a force -Cv², where C is a con- stant and v is its speed. Find the time required for it to travel dis- tance s if it is initially moving with speed vo. Show that the result is reasonable for short times.
- Leaving the distance between the 87 kg and the 772 kg masses fixed, at what distance from the 772 kg mass (other than infinitely remote ones) does the 63.9 kg mass experience a net force of zero? Answer in units of m.A greater force is required to move an object with a greater mass than one with a smaller mass. Select one: O True O FalseAsap plzzzz
