Question

Given that S = 2t + 1/23t2? (In SI units), using this equation find the initial velocity
1) 2m/s
2) 3m/s
3) 4m/s
4) Om/s​

Answer 1

Explanation:

here,

$s=2t+\frac{1}{2}$*3t²

differentiate aboub equation

$\frac{ds}{dt}=u=2+\binom{3}{2}*2t$

u=2+3t

this is initial velocity of partical at instant of time 't'

Answer 2

Answer:

U=2m/s

Explanation:

s=2t+1/2(3t)^2 this is 1 equation

we know that, s=ut+1/2×at^2 this is 2 equation

compare 1&2

In 1 equation u=2m/s , a=3m/s^2

initial velocity =u=2m/s
