Check a physics "Q".
For this question i got 18m/s is this correct?
A car travels in a circular path of radius 20.0 m. If the coefficient of static friction is 0.72, find the maximum speed at which the car can travel around the curve without skidding. Assuming g=10m/s^2.
A block of mass 8.0 kg is on the verge of sliding down a 450 incline. What is the magnitude of the horizontal force F, if the coefficient of static friction between the block and the incline is 0.35? I'm really stuck...appreciate any help. Thanks!
A horizontal force of 45N is required to accelerate a 5kg block by 4m/s2 on a horizontal surface. I need to find the coefficient of kinetic friction between the block and the surface by assuming g= 10m/s2. How would I go about doing this?
An elevator is moving upward with an acceleration of 1.0 m/s2. The total mass of the elevator and the passengers is 800kg. I need to find the tension in the elevator cable assuming g=32ft/s2. Need help, beginner in physics. Thanks!
