Question

class 9 chapter force and law of motion.​

Answer 1

Explanation:

100N is required to move an object of 50kg weight in 2ms-2

Answer 2

Provided that:

• Mass of a body = 50 kg
• Acceleration = 2 m/s²

Don't be confused! Acceleration is the one word for rate of change in velocity.

To calculate:

• The force

Solution:

• The force = 100 Newton

Using concept:

• Force formula

Using formula:

• F = ma

(Where, a denotes acceleration, F denotes force and m denotes mass)

Required solution:

Required solution: ~ We just have to put the values according to the formula, and have to carry on!

$:\implies \sf Force \: = mass \times acceleration \\ \\ :\implies \sf F \: = m \times a \\ \\ :\implies \sf F \: = ma \\ \\ :\implies \sf F \: = 50(2) \\ \\ :\implies \sf F \: = 50 \times 2 \\ \\ :\implies \sf F \: = 100 \: N \\ \\ :\implies \sf Force \: = 100 \: Newton\\ \\ {\pmb{\sf{Henceforth, \: solved!}}}$
