Mass is the measure of the amount of matter in an object.
The gravity on <span>an object depends on two things: </span>mass<span> of the objects being attracted and the distance between the objects is needed to find gravity. </span>
The amount of force required to accelerate 57kg skier with an acceleration of 4m/s² is 228N.
<h3>How to calculate force?</h3>
Force is a physical quantity that denotes ability to push, pull, twist or accelerate a body and which has a direction and is measured in a unit dimensioned in mass × distance/time².
The force applied on an object can be calculated using the following formula:
Force = mass × acceleration
According to this question, a skier with mass 57kg accelerates at 4m/s². The force required can be calculated as follows:
Force = 57kg × 4m/s²
Force = 228N
Therefore, the amount of force required to accelerate 57kg skier with an acceleration of 4m/s² is 228N.

You use long division.
Find the largest number whose square is less than or equal to the number in the leftmost group (55 < 30 < 66). Take this number as the divisor and the quotient with the number in the leftmost group as the dividend (30). Divide and get the remainder (5 in this case).
Bring down the next pair 58. Add the divisor with the quotient and enter it with a blank on its right. Guess a largest possible digit to fill the blank which will also become the new digit in the quotient, such that when the new divisor is multiplied to the new quotient the product is less than or equal to the dividend. In this case 105 × 5 = 525, so we choose the new digit as 5. Get the remainder.
Bring down the next pair 09. Add the divisor with the quotient and enter it with a blank on its right. Guess a largest possible digit to fill the blank which will also become the new digit in the quotient, such that when the new divisor is multiplied to the new quotient the product is less than or equal to the dividend. In this case 1103 × 3 = 3309, so we choose the new digit as 3. Get the remainder.
Put the decimal point.
End of division (Remainder is 0 and next digit after decimal is 0).

Answer: 7291.2 joules
Explanation:
Work is done when force is applied on an object over a distance.
Thus, Workdone = Force X distance
Since Distance moved by box = 12 metres
mass of box = 62kg
Acceleration due to gravity when box was lifted is represented by g = 9.8m/s^2
Recall that Force = Mass x acceleration due to gravity
i.e Force = 62kg x 9.8m/s^2
= 607.6 Newton
So, Workdone = Force X Distance
Workdone = 607.6 Newton X 12 metres
Workdone = 7291.2 joules
Thus, 7291.2 joules of work was done.
Liquid to a gas hence the name water vapor
