what is the value of work done on an object when a 0.1*10^2 newton force moves it 30 meters and the angle between the forces and the displacement is 25

A 35kg child moves with uniform circular motion while riding a horse on a carousel. The horse is 3.2m from the carousel's axis of rotation and has a tangential speed of 2.6 m/s. What is the child's centripetal acceleration?

What is the acceleration of this object? The object's mass is 60 kg. Use the formula for Newton's Second Law to solve for acceleration A=F/m A) 0 m/s2 B) 3.3 m/s2 C) 6.7 m/s2 D) 10 m/s2

What is the fundamental frequency if the tension in the string is halved?

Why does an ice cube feel cold when you touch it?

A locomotive is pulling 15 freight cars, each of which is loaded with the same amount of weight. The mass of each freight car (with its load) is 37,000 kg. If the train is accelerating at 0.

How do speed and acceleration differ

If your mass is 20kg, and you stand on the scale (witch is your force), and the acceleration due to gravity is10m/s^2, what does the scale says your weight is?
