1

The given formula is v=u+atv=u+at

The given values are u=2, a=-5, t=\frac{1}{2}t=

1

To find the value of v,

Substitute all given values into the formula,

v=u+atv=u+at

v=2+(-5)(\frac{1}{2})v=2+(−5)(

)

v=2-\frac{5}{2}v=2−

5

v=\frac{4-5}{2}v=

2

4−5

v=\frac{-1}{2}v=

Answer 2

v = u+at

v = 2+5×1/2

v = 4.5 m/s
