23. A car traveling on a flat (unbanked), circular track w accelerates uniformly from rest with a tangential accel- eration of 1.70 m/s². The car makes it one-quarter of the way around the circle before it skids off the track. From these data, determine the coefficient of static friction between the car and the track.

A stuntman drives a car (without negative lift) over the top of a hill, the cross section of which can be approximated by a circle of radius R= 250 m. What is the greatest speed at which he can drive without the car leaving the road at the top of the hill in km/h? R Lütfen birini seçin: O A. 178 O B. 221 O C. 135 O D. 150 O E. 205

A 1500 kg car moving on a flat, horizontal road negotiates a curve. If the radius of the curve is 1600 m and coefficient of static friction between the tires and the road (µ,) is 0.1, what is the maximum speed (in m/s) the car can have and still make the turn successfully. (g=10 m/s³) O a. 20 O b. 30 Oc. 10 O d. 40

A cellphone steps into a “Graviton” and stands up against the frictionalwall. The Gravitron starts to spin and the floor lowers below the cellphone butthe cellphone does not accelerate downwards, she has no net force vertically. Assume:● The radius of the Gravitron is 7.5 m● The cellphone has a tangential velocityof 15 m/s● The man has mass M Determine: Determine the minimum coe cient of static friction between the wall and the cellphone.

Pls help ASAP.

C. Which of Newton's Laws applies in reference to your body pulls to the right when the car turns to the left? 6. Describe what tangential velocity is in terms of swinging the bucket in a vertical circle and then letting the bucket go. 7. True or False: The centripetal force has the same direction as the centripetal acceleration. 8. Write the formula of cent etal acceleration in terms of tangential velocity. 9. Write the Formula of centripetal force in terms of tangential velocity.

11. A crate of eggs is located in the middle of the flatbed W of a pickup truck as the truck negotiates a curve in the flat road. The curve may be regarded as an arc of a circle of radius 35.0 m. If the coefficient of static fric- tion between crate and truck is 0.600, how fast can the truck be moving without the crate sliding?

A 2000 kg car going at a steady speed of 18.0 m/s takes a curve with a 50.0 m radius. The road is level. 1. Draw an FBD. 2. Find the centripetal force of the car. 3. Find the frictional force of the car. 4. Find the weight of the car. 5. What is the minimum value that the coefficient of static friction between the tires and the road must have so that the car takes this curve without slipping?

A 10 m/s В A 1000-kg Jeep travels along a straight 500-m portion of highway (from A to B) at a constant speed of 10 m/s. At B, the Jeep encounters an unbanked curve of radius 50 m. The Jeep follows the road from B to C traveling at a constant speed of 10 m/s while the direction of the Jeep changes from east to south. ... 50 m N C W E S What is the magnitude of the acceleration of the Jeep as it travels from B to C?
