Car a uses tires for which the coefficient of static friction is 0.169 on a particular unbanked curve. the maximum speed at which the car can negotiate this curve is 23.7 m/s. car b uses tires for which the coefficient of static friction is 0.826 on the same curve. what is the maximum speed at which car b can negotiate the curve?

Explanation:

For unbanked road the maximum friction force will provide centripetal force to the car.

So here we will have

Since we know that centripetal force here is due to friction force

now for two cars we will have

also we have

now by division of two equations

so we will have

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper

that would be because of both gravity and friction. so     c
