Question

displacement time graph of an object of mass 2 kg is shown in figure the force required to move the object for first 3 second is.

Answer 1

Answer: F = 0

Explanation:

Force = mass × acceleration

Acceleration is change in velocity per unit time:

a=Δ∨/Δt

From the displacement time graph, we come to know that velocity is constant having magnitude:

$v=\frac{6m-0m}{3s-0s}=2m/s$

⇒Δ∨=0

⇒a=0

⇒F=m×a=0

Therefore, the force required to move the object in first three minutes is 0.

Answer 2

Answer:

obviously 0 like ypur mark
