Given:

Force(F): 100 N

Acceleration: 10 m/s^2

Now we know that

F= mx a

Where F is the force acting on the object which is measured in Newton

m is the mass of the object measured in Kg

a is the acceleration measured in m/s^2

Substituting the given values in the above formula we get

100= 10m

m= 10 Kg

Force = Mass x Acceleration

To solve for Mass, we need to divide both sides by the acceleration.

Force / Acceleration = Mass

Since our Force = 100N and our Acceleration = 10m/s^2, we can just plug these values into the equation that is = Mass.

Force / Acceleration = Mass

Mass = (100N)/(10m/s^2) = 10 kg

The mass of a regulation tennis ball is 57 g. The ball is in contact with the tennis racket for 30 ms. The ball was served at 73
yaroslaw [1]

Answer:

Correct answer:  F₂ = 104.5 N

Explanation:

Given:

m = 57 g = 57 · 10⁻³ kg

Δt = 30 ms = 30 · 10 ⁻³ seconds

V₁ = 73.14 m/s   service speed

V₂ = 55 m/s  returned speed

M = m · V  Momentum or Impulse

You forgot to indicate what time the ball contact when returning.

We will assume that the time is the same Δt = 30 ms = 30 10 ⁻³ seconds.

The formula for calculating force is according to Newton's second law is:

F = ΔM / Δt = m · ΔV / Δt

Force during service is:

F₁ = 57 · 10⁻³ · 73.14 / 30 · 10 ⁻³ = 138.97 N

F₁ = 138.97 N

Returned force:

F₂ =  57 · 10⁻³ · 55 / 30 · 10 ⁻³ = 104.5 N

F₂ =  104.5 N

Tp-18 what should you do when operating a boat in large waves and high wind?
deff fn [24]

1) Try to head into the waves at some slight angle and the speed of the boat should be reduced. 

2) In order to ride up and over the waves, the speed of the boat should be slow. 

3) The less the speed of the boat, and the less strain will be put on the hull and superstructure.
