Question

a body moves from rest with a uniform acceleration and travels 270m in 3s. Find the velocity of the body at 10s after the start​

Answer 1

Answer:

$\huge{♥}{\underline{\mathtt{\red{A}\pink{η}\green{s}\blue{ω}\purple{ε}\orange{я}}}}{♥}$

u=0,s=270m,t=3s

s=ut+ $\dfrac{2}{1}at²$

270=0×3+ $\dfrac{2}{1}$×a×3²

a=60 m/s²

Now putting the value of a in v=u+at,

Velocity after t=10s is given by

v=0+60×10=600 m/s

Hence Velocity is 600 m/s
