Question

A car increases its velocity from zero to 97 km/h in 8.4 s. What is its acceleration?

Answer 1

Answer:

$a=\frac{v-u}{t}$

$v=$final velocity =97km/h(change to m/s) =26.9m/s NEVER FORGET TO DO THAT BECAUSE TIME IS GIVEN IN SECONDS

$u=$initial velocity  0 m/s

$t=$time 8.4s

$a=\frac{26.9-0}{8.4}$

$a=$ $3.2m/2^{2}$
