Question

a racing car has a uniform acceleration of 4 metre per second square. what distance will it cover in 10 seconds after start

Answer 1

GIVEN:-

$\large\sf\green{Acceleration(a)=4m/s}$

$\large\sf\green{Initial\:velocity(u)=0m/s}$

$\large\sf\green{Time(t)=10s}$

$\large\sf\green{Distance\:covered(s)=?}$

We Know that,

$\longrightarrow$$\large\sf\pink{s = ut + \frac{1}{2} {at}^{2} }$

$\longrightarrow$$\large\sf\pink{s = 0 \times 10 + \frac{1}{2} \times 4 \times {(10)}^{2} m}$

$\longrightarrow$$\large\sf\pink{s=2×100m}$

$\longrightarrow$$\large\sf\pink{s=200m}$
