Question

the velocity of a body is given by v=At*t+Bt+C.if v and t are expressed in SI,what are the units of A,B and C

Answer 1

HEY BUDDY..!!!

HERE'S THE ANSWER..

_________________________________

♠️ As we know v is velocity and t is time ,

✔️ SI unit of velocity ( m / s )

✔️ SI unit of time ( s )



♠️ Here is a rule , if we add or subtract any term which has same unit ; it will have no effect on its unit , For example = 5 Kg + 2 Kg = 7 Kg , Here SI unit is in Kg


▶️ Writing Eqn in terms of SI unit

=> m / s = A . s^2 + B s + C

⏺️ Now comparing each .

=> m / s = A . s^2

=> [ A = m / s^3 ]✔️✔️

⏺️

=> B . s = m / s

=> [ B = m / s^2 ]✔️✔️

⏺️

=> [ C = m / s ]✔️✔️



HOPE HELPED..

JAI HIND..

Answer 2

v = m/s , t = s

m/s=As^2+Bs+C

on comparison

A= m/s^3

B= m/ s^2

C = m/ s
