A wheel rotates without friction about a stationary horizontal axis at the center of the wheel.A constant tangential force of 75N is applied to the rim of the wheel.The wheel has a radius of 0.13m.The wheel has an angular speed of 14.5rev/s after 3.70s.Wh...

In the amusement park ride known as Magic Mountain Superman, powerful magnets accelerate a car and its riders from rest to 45 m/s (about 100 mi/h) in a time of 7.0 s. The combined mass of the car and riders is 5.5 × 103 kg. Find the average net force exer...

What is the weight density of water?

Question on Torque. is T=Fl the same as T=FD?

Each wheel is a solid disk of mass 2.0 kg. On the horizontal surfaces the center of mass of each wheel moves with a linear speed of 6.0 m/s. (a1) What is the algebraic expression for the total kinetic energy KEtotal of the rolling wheel? Express your answ...

Two identical wheels are moving on horizontal surfaces. The center of mass of each has the same linear speed. However, one wheel is rolling, while the other is sliding on a frictionless surface without rolling. Each wheel then encounters an incline plane....

How am I incorrect though? I've used a kinematics equation v=vo+at, which resulted in me getting my acceleration and plugged in Newton's 2nd law as well as multiplying the acceleration by the given mass, resulting in an answer similar to this, only I beli...

Let me show my process: v= 45 m/s vo= 0 m/s t= 7.0 s m = 5.5 x 10^3 kg a=? F=? To solve for acceleration, I've used a kinematics equation: v=vo+at a= (45 m/s) / (7.0 s) = 6.428 m/s^2 Then we use Newton's 2nd law: F=ma F= (5.5 x 10^3 kg)(6.428 m/s^2) F is...
