sorry I didn't know that

Answer 2

Given: A driver loads machines into his truck by lifting them directly.Each machine

weighs 60Kg and the truck platform is at a height of 90 cm above the ground.

To find: We have to find the force used to lift a machine.

Solution:

According to Newton's Second law

F=m×g

Where F is the force having unit Newton.

m is the weight of the machine.

g is the gravity.

Here, given that m=60kg.

$g = 10m {s}^{ - 2}$

Putting the values of m and g in the above formula of force we get

$= 60 \times 10 \\ = 600$

The force he have to use to lift the machine is 600N.
