At a playground, a child slides down a slide that makes a 42° angle with the horizontal direction. The coefficient of kinetic friction for the child sliding on the slide is 0.20. What is the magnitude of her acceleration during her sliding?

Explanation:

Given,

The angle of the slide=

The mass of the child is= m

coefficient of friction = 0.20

when she slides down now apply Newton's law

therefore the acceleration

hence, the magnitude of acceleration during her sliding is equal to  

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

compass can be used day and night, cloudy or sunny
