What is the magnitude of the centripetal pressure that need to act on an item of fixed 1.0 kg to do it relocate along a circular path of diameter 1.0 m, perfect a one every 1.0 s? offer your answer to the nearest newton.


A vehicle with fixed 360 kg travels at continuous speed along a one path roughly a flat roundabout. The radius that the roundabout is 12 m. The auto takes a time of 28 s to completely travel around the roundabout.

What is the friction force in between the wheels of the car and the surface of the road? offer your answer come the nearest newton.

What is the coefficient of static friction because that the wheel of the vehicle on the surface of the road? usage a worth of 9.8 m/s2 for the acceleration due to gravity. Offer your price to three decimal places.


A spinning disk has actually a string that holds a little sphere that has a massive of 16 g. The string is suspended indigenous a allude at a negligible distancefrom the center, as presented in the diagram. The disk rotates uniformly roughly itscenter through an angular velocity that 24 rad/s. The string provides an edge of
