How is acceleration of the cart related to the amount of force acting on it? the strips of it?

Answers

We know that Newton's Second Law of Motion states that -

                                        F = ma

It is clear that acceleration is directly proportional to the Force acting on a body. So, the amount of Force acting on a body is directly proportional to the acceleration, when the mass is constant.
Force on the cart is directly proportional to the acceleration.

This relationship was given be Sir Isaac Newton.

Mathematically ;

F = ma

Where F is force, a is acceleration and m is constant of proportionality , also known as mass.

2. The Moon takes 27.25 days to make one revolution around the Earth. Calculate how
many seconds it takes for the Moon to make one revolution around the Earth.

Answers

Answer:

1. 15.64 m/s

2. 2,354,400 seconds

Explanation:

1. 1mile is equivalent to 1609metres and 1hour is equivalent to 3600sec.

35mph = (35×1609)/3600

= 56315/3600

= 15.64 m/s

2. Note that 1 day ===> 24hrs

60min ==> 1hr

60sec ===> 1min

Thus 27.25 days = 27.25×24×60×60

= 2,354,400 seconds
