Question

a body is travelling with a velocity 30 m/s. it is given an acceleration 5m/s².what will be its velocity after 4s?​

Answer 1

Answer:

50m/s

Explanation:

$a=\frac{v_{2}-v_{1}}{t} \\5=\frac{v_{2}-30}{4}\\5*4={v_{2}-30}\\20={v_{2}-30}\\20+30={v_{2}}\\{v_{2}}=50$

Hope the answer helped

Answer 2

Answer:

velocity after 5 seconds = 50 m/s
