a girl pushes her little brother down a snowy hill on a sled and he rides quickly to the bottom of the hill

which one of Newton's Laws is this ​

Answers

Answer 1

Answer:

Newton's First Law of Motion.

Explanation:

Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.

In physics, Sir Isaac Newton's First Law of Motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.

In this scenario, a girl pushes her little brother down a snowy hill on a sled and he rides quickly to the bottom of the hill. The push from the little boy's sister is the external force acting on him and consequently, causing him to be in motion down the snowy hill.

A .Spring A had a higher elastic potential energy than Spring B.
B. Spring A's spring constant is higher than Spring B's.

Answers

Answer: instantaneous speed.

Explanation: A highway speed limit posted as 90km/hr would be the instantaneous speed because it’s just the speed for that moment.

While driving his sports car at 20.0 m/s through a residential neighborhood, Royston

Answers

Answer:

1.67s

Explanation:

Given parameters:

Initial velocity  =  20m/s

Acceleration  = 6m/s²

Final velocity  = 30m/s

Unknown:

Time taken  = ?

Solution:

Acceleration is the rate of change of velocity with time. It is mathematically expressed as;

 Acceleration = [tex]\frac{v - u }{t}[/tex]  

v is the final velocity

u is the initial velocity

 t is the time taken

            6  =[tex]\frac{30 - 20}{t}[/tex]  

            6  = [tex]\frac{10}{t}[/tex]  

              10  = 6t

              t  = 1.67s
