The car moves along a curve with a radius of 100 m. At a speed of 10 m / s. What is the centripetal acceleration of a car?

R = 100 m.

V = 10 m / s.

a -?

Since the direction of speed changes when driving on a rounded path, the car has centripetal acceleration. The centripetal acceleration a is determined by the formula: a = V ^ 2 / R, where V is the speed of movement, R is the radius of the trajectory rounding.

a = (10 m / s) ^ 2/100 m = 1 m / s2.

Answer: the car is moving with centripetal acceleration a = 1 m / s2.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
