• An object of mass 5 kg is moving with a velocity of 10 m/s. A force is applied so that in 15 s, it attains a velocity of 25 m/s. What is the force applied on the object ?

$\huge \bf \color{blue} \mathfrak{Solution : - }$

Mass = 5kg

Initial Velocity = 10m/s

Final Velocity = 25m/s

Time = 15s

Acceleration

= (Final Velocity - Initial Velocity)/Time

→ Acceleration = (25m/s - 10m/s)/15s

→ Acceleration = 15m/s/s

→ Acceleration = 15m/s²

Force = Mass × Acceleration

→ Force = 5kg × 1m/s²

→ Force = 5kgm/s² or 5N

Force = 5N
