Question

c. A car was running with a velocity of 20m/s. what will be its velocity after 30s if it's acceleration is 5m/s2​

Answer 1

$\large \mathfrak{Solution : }$

let's use first equation of motion to solve this ;

• $\boxed{ \boxed{ v = u + at}}$

• $v = 20 + (5 \times 30)$

• $v = 20 + 150$

• $v = 170 \: \: m/s$

Velocity after 30 seconds = 170 m/s
