The SI / Metric unit of force is the ' Newton '.
1 newton is the force that accelerates 1 kg of mass at the rate of 1 m/s² .
Answer:
Final velocity of the elevator will be 4.453 m/sec
Explanation:
Let mass is m
Acceleration due to gravity is g m/sec^2
Distance s = 2.2 m
As the elevator is moving upward so net force on elevator
So according to question
0.46 mg = ma
a = 0.46 g
a = 0.46×9.8 = 4.508
Initial velocity of elevator is 0 m/sec
From third equation of motion
So final velocity of the elevator will be 4.453 m/sec
It's an insulator because it's glass which means it stops the current
The symbol c represents the speed of light.
<em>≈ 0.47 m/s²</em>
<em>Hi there !</em>
<em>Acceleration formula</em>
<em>a = (v₂ - v₁)/t</em>
<em />
<em>a = (26.8m/s - 24.8m/s)/4.3s</em>
<em>= (2m/s)/4.3s</em>
<em>≈ 0.47 m/s²</em>
<em>Good luck !</em>
