To Accelerate a vehicle to a rate of 4 m/s²,80 N force is required. Find the mass of vehicle. Find the mass of vehicle.​

Answer 1

Answer:

The mass of vehicle is 20kg.

Given:

• Acceleration of a vehicle, a = 4 m/s².
• Force required to accelerate a vehicle, F = 80 N.

To Find:

• The mass of a vehicle.

Solution:

To find the mass of vehicle = ?

F = ma

Where,

• F = Force
• m = mass of vehicle
• a = acceleration of vehicle

$\large \bf m = \dfrac{F}{a}$

Where,

• m = mass of vehicle
• F = Force
• a = acceleration of vehicle.

=> 80 = (m)(4)

=> 80 = 4m

=> m = 20kg.

Therefore,

Mass of the vehicle is 20kg.

Answer 2

We already know the formula F = MA

= $\sf{M =\frac{F}{A}}$

So,

$\sf{\frac{80}{4}}$

= $\sf{20\:m/s^2}$

∴ The mass of the vehicle is $\sf{20\:m/s^2}$
