Question

A car changes its velocity from 10m/s to 2m/s.distance is 10m then find acceleration amd time

Answer 1

Explanation:

acceleration is 8 m/s

time is 1sec

Answer 2

$\huge{\boxed{\bf{Answer:-}}}$

Given:-

u = 10 m/s

v = 2 m/s

s = 10 m

a = ?

_______________________

Formula Used:-

v² - u² = 2as

Solution

2² - 10² = 2×a×10

4 - 100 = 20a

-96 = 20a

$a = \frac{ - 96}{20}$

a = -4.8 ${ms^{-2}}$

Time

Formula

v = u + at

2 = 10 + (-4.8)(t)

-8 = -4.8t

t = 1.667 s
