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 * 30)`

• 
  `v = 20 + 150`

• 
  `v = 170 \: \: m/s`

Velocity after 30 seconds = 170 m/s
