Question

If a Ferrari, with an initial velocity of 10 m/s, accelerates at a rate of 5 m/s2 for 3 seconds, what will its final velocity be?

Answer 1

25 m/s

Step-by-step explanation:

Formula of acceleration is:

`a=(v-u)/(t) \\`

where,

v is the final velocity

u is the initial velocity

a is the acceleration and

t is the time

so plugging in the values we get,

`a=(v-u)/(t) \\\\5=(v-10)/(3) \\\\15=v-10\\15+10=v\\v=25\ m/s\\`
