Newton's first law is sometimes known as the law of inertia. It is the law that states that an object at rest will stay at rest and an object in motion will stay in motion unless a force acts upon it. For example, if I was working with a wrench in space an it slipped, it would keep on going in one direction with a constant speed unless it hits something. Hope this helps!

How long will it take for a car to accelerate to come to a stop if it is traveling at 20m/s and the car has a maximum decelerati

Pachacha [2.7K]

When the car comes to a stop, the final velocity must be 0 m/s.
Since the car js decelerating in a forward direction, acceleration must be negative.

final v = initial v + a•t
0 = 20 + (-6)t
t = 3.33s

The displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s

Veseljchak [2.6K]

Answer:

$v_{avg} = 0$

Explanation:

The object is moving to and fro about its mean position

and the equation for its displacement is given as

$s = 5 sin(\pi t) + 5 cos(\pi t)$

now in one complete time period we know that the the object will complete its one oscillation

So the change in the position of the object in one complete time period will be ZERO

so here we can say that

$v_{avg} = \frac{displacement}{time}$

since change in position is zero

so displacement = 0

$v_{avg} = 0$
