Question

a constant force acts on an object of mass 8kg for a duration of 4s .it increases from 5m/s to 10/ms .find the magnitude of applied force​

Answer 1

Answer:

$\huge\underline{\colorbox{pink}{Answer}}$

Given :-

• Initial Velocity, u = 5 m/s
• Final Velocity, v = 10 m/s
• Time, t = 4 s
• Mass, m = 8 kg

To find :-

• Magnitude of applied force?

Solution :-

We know that,

★ Acceleration = (final velocity - initial velocity)/time

➻ a = (v - u)/t

➻ a = (10 - 5)/4

➻ a = 5/4

➻ a = 1.25 m/s²

Now, Finding force applied on object,

We know that,

★ Force = Mass × Acceleration

➻ F = m × a

➻ F = 8 × 1.25

➻ F = 10 N

∴ Hence, 10 N constant force is applied on an object..
