Question

What impulse is imparted when a 30-N force is applied to an object for 2 s?

Answer 1

Answer:

60kg/m.s^2

Explanation:

Answer 2

Given

Force = 30 N

Time = 2 s

To Find

Impulse

Solution

We know that

$\rm \longrightarrow J=F \Delta t$

Here

• J = Impulse
• F = Force
• Δt = Time

Units

• J = Newton second (N s)
• F = Newton (N)
• Δt = Second (s)

According to the question

We are asked to find Impulse

Therefore

We must find "J"

Given that

Force = 30 N

Time = 2 s

Hence

• F = 30 N
• Δt = 2 s

Substituting the values

We get

$\rm \longrightarrow J=30 \times 2 \ N \ s$

Therefore

$\rm \longrightarrow J=60 \ N \ s$

Hence

Impulse = 60 N s
