Question

Suberin
If a car traveling at 10 m/s accelerates uniformly at 5 metre per second
squared. Its velocity after 10 seconds will be: *
O 60 m/s
O 50 m/s
O 100 m/s
O 80 m/s​

Answer 1

Given

u ( Initial velocity ) = 10 m/s

a ( acceleration ) = 5 m/s^2

t ( time taken ) = 10 s

By 1st equation of motion, we have

$v = u + at = 10 + 5 \times 10$

$v = 10 + 50 = 60$

Thus final velocity is 60 m/s
