Question

An antelope trots through the grasslands at a velocity of 3 m/s. Suddenly, a lion begins to chase the antelope. If the antelope accelerates at a rate of 2 m/s2, what is the antelope's final velocity after 10 seconds?

Answer 1

Step-by-step explanation:

To find the final velocity, we would apply one of Newton's formula for motion which is expressed as

v = u + at

where

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time

From the information given,

u = 3

v = ?

a = 2

t = 10

By substituting these values into the formula, we have

v = 3 + 2 * 10

v = 3 + 20 = 23

the antelope's final velocity = 23 m/s
