Question

v=u+at find v u=2 a=-5 t=1/5

Answer 1

Answer:

v=u+at

here u=2, a= -5, t=1/5

v=2-5.1/5

=> v=2-1

=> v=1

Answer 2

Answer:

By First equation of newton

$v = u + at$

here,

u is initial velocity

v is final velocity

a is acceleration

t is time

$u = 2 \\ a = -5 \\ t = \frac{1}{-5}$

Find v = ?

Putting value in newton's first equation

$v = u + at$

$v = 2 + 5 \times \frac{1}{-5}$

$v = 2 + (-\frac{5}{5})$

$v = 2 - 1 = 1$

so, the final velocity is 1.
