Question

a car initially at rest Move with an acceleration of 8m/s find displacement of the car in 10 second


​

Answer 1

Answer:

>> Displacement = 400m

Explanation:

Given:-

>> Initial velocity = 0m/s

>> Acceleration = 8m/s^2

>> time = 10 seconds

To FIND:

>> Displacement =?

Procedure:-

>> USING SECOND EQUATION OF MOTION :-

$\boxed{\implies \bf s = ut+ \frac{1}{2} at^2}$

>> Plugging the known values in:-

$\sf \implies s = 0 \times \dfrac{1}{2} \times 8 \times (10)^2$

>> Simplifying further:-

$\implies \sf s = 0 + 1 \times 4 \times 100$

>> Final Answer:-

$\implies \sf s = 400m$

Extra Information:-

• What is momentum ?

The linear momentum of a body is defined as product of mass and velocity.

• Odometer is a device used to measure the distance traveled by vehicle.

• Distance is directly proportional to time².

• If a body travels unequal distance in equal interval of time then it is aid to be non uniform motion.

• If a body travels equal distance in equal interval of time then it is aid to be in uniform motion.

• Instataneous speed is the speed in particular instance of time.

Answer 2

$\huge\red{\underline{❥Solution}}$

USING SECOND EQUATION OF MOTION :-

$\large{\implies \bf s = ut+ \frac{1}{2} at^2}$

Plugging the known values in:-

$\sf \implies s = 0 \times \dfrac{1}{2} \times 8 \times (10)^2$

$\implies \sf s = 0 + 1 \times4 \times 100$

$\implies \sf s = 400m$
