Question

a racing car has a uniform acceleration of 4ms^-2.Then distance will it cover in 10s is

Answer 1

Answer:

Distance travelled by racing car = 200m

Step-by-step Explanation:

Given :

Acceleration = 4 m/s-²

Time = 10s

To find :

The distance travelled by the racing car

Taken :

To find the distance travelled by the racing car use the equation of motion -:

$\boxed{\sf{s=ut+\dfrac{1}{2}a{t}^{2}}}$

Where,

s = Distance

u = Initial velocity

t = Time

a = Acceleration

Solution :

$:\implies\sf{s=0\times10s+\dfrac{1}{\cancel{2}}\times\cancel{{4m/s}^{-2}}\times{10s}^{2}}$

$:\implies\sf{s=0+2\times(10\times10)}$

$:\implies\sf{s=0+2\times100}$

$:\implies\sf{s=0+200}$

$:\implies\sf{s=200m}$

So , the distance travelled by the racing car is 200 m .
