Q1. A 2.62 kg mass attached to a light string rotates on the horizontal, frictionless table. The radius of the circle is 0.4207 m, and string can support a mass of 14.70 kg before breaking.
The acceleration of gravity is 9.80 m/s2.
What maximum speed can the mass have before the string breaks?
Q2. An object is dropped from an altitude of 1.10R above Earth's surface. Where R is the radius of the earth. What would be the speed of the object just before it hits Earth?
How much force, in Newtons, is needed to accelerate a truck with a mass of 1500 kilograms from a full stop to 40 m/s in 10 seconds if the rate of acceleration is constant.
It's found that string is set into oscillation only at the frequency 880 Hz and 1320 Hz as the frequency of an oscillator is varied over the range 500-1500 Hz. What is the tension in the string.
A 12 kg mass starts from rest and slides down an inclined plane 8.0 10-1 m long in 0.9 s. What net force is acting on the mass along the incline?
A person with a mass of 103 kg is standing on a scale that reads weight in newtons inside of an elevator. If the elevator accelerates upward at 3.2 m/s2, what does the scale read.
