Question

a car has an acceleration of 2.5m/s2. the force accelerating the car is 3750 N.
a) state what is meant by acceleration?
b)calculate the mass of the car?

Answer 1

Explanation:

A)

ACCELERATION :

DEFINITION:

The rate of chamge of velocity of a body is known as acceleration

FORMULA:

$a = \frac{vf - vi}{t}$

or

$a = \frac{force}{mass}$

QUANTITY :

It is a vector quantity

UNIT:

$m {s}^{ - 2}$

B)

GIVEN:

FORCE=F=3750N

ACCELERATION=a=2.5m/s^-2

TO FIND:

MASS=m=?

FORMULA:

$m = \frac{f}{a}$

SOLUTION:

As

$m = \frac{f}{a}$

putting values in formula

$m = \frac{3750}{2.5}$

$m = 1500kg$

Answer 2

Question :-

A car has an acceleration of 2.5m/s². The force accelerating the car is 3750 N.

a) State what is meant by acceleration?

b) Calculate the mass of the car?

Solution :-

A)

● Acceleration is the rate of change of velocity with respect to time.

● If an object is accelerating, then it is changing its velocity.

● It is a Vector Quantity.

● Unit Of Acceleration = m/s²

● Formula Of Acceleration :-

Acceleration = (v - u)/t.

B)

Given :-

● Force = 3750 Newton.

● Acceleration= 2.5m/s²

To Find :-

● Mass Of the Car.

Solution :-

We know that,

Force = Mass × Acceleration.

➠ 3750 = Mass × 2.5

➠ Mass = 3750 ÷ 2.5

➠ Mass = 1500 kg.

Therefore, Mass Of Car = 1500 kg.
