Question

class 9 chapter force and law of motion.​

Answer 1

Provided that:

• Mass of a car = 1000 kg
• Acceleration = 5 m/s²

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

To calculate:

• The force

Solution:

• The force = 5000 Newton

Using concept:

• Force formula

Using formula:

• F = ma

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

Required solution:

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

$:\implies \sf Force \: = mass \times acceleration \\ \\ :\implies \sf F \: = m \times a \\ \\ :\implies \sf F \: = ma \\ \\ :\implies \sf F \: = 1000(5) \\ \\ :\implies \sf F \: = 1000 \times 5 \\ \\ :\implies \sf F \: = 5000 \ N \\ \\ :\implies \sf Force \: = 5000 \ Newton \\ \\ {\pmb{\sf{Henceforth, \: solved!}}}$

Answer 2

Answer:-

• Mass=1000kg
• Acceleration=5m/s$^2$

We know

$\boxed{\sf Force=Mass\times Acceleration}$

➜F=ma

➜Force=1000×5

➜Force=5000Newton

➜Force=5000N
