Question

Find 's', If u=2m/s , v=5m/s and a=10m/s²​

Answer 1

Answer:

s= 21/20 m.

Explanation:

$we \: have \\ {v}^{2} - {u}^{2} = 2as \\ s = \frac{( {v}^{2} - {u}^{2} )}{2a} \\ putting \: the \: given \: values \\ s = \frac{21}{20} m$

Answer 2

Answer:

s=1.16m/s

Explanation:

By using 2as=v²-u²

2(10)s=(5)²-(2)²

20s=25+4

20s=29

s=29/25

s=1.16m/s
