Answer:

0.62

Explanation:

Ff = mg = 52 N

Since the speed is constant, the friction

force equals the force exerted by the

girl, 36 N.

Ff = ukFn

so uK = Ff/Fn

= 36 N/52 N

= 0.69

What is the difference between acceleration and linear acceleration?
Akimi4 [234]

Explanation:

Linear acceleration is a type of acceleration of a body along a straight path or line.

Acceleration is defined as the rate of change of velocity with time.

  Acceleration = \frac{Change in velocity}{time}

There are different types of acceleration .

  • linear acceleration is used to describe the rate of change of velocity of a body along a straight path with time.
  • centripetal acceleration is the rate of change of velocity of a body traveling along a circular path with time. It is directed towards the center.
  • Angular acceleration is the rate of change of angular velocity.
