Question
A ball of mass 150 g moving with an acceleration 20m/s2is hit by a force, which act it for 0.1 sec. The impulsive force isSelect an answerA0.5 N.SB0.1 N–1C0.3 N–sD1.2 N–s
Solution
The impulsive force can be calculated using the formula:
Impulse = Force x Time = Mass x Change in Velocity
Given: Mass (m) = 150 g = 0.15 kg (since 1 kg = 1000 g) Acceleration (a) = 20 m/s² Time (t) = 0.1 s
First, we need to find the change in velocity (Δv), which can be calculated using the formula:
Δv = a x t
Substituting the given values:
Δv = 20 m/s² x 0.1 s = 2 m/s
Now, we can calculate the impulse:
Impulse = m x Δv = 0.15 kg x 2 m/s = 0.3 N.s
So, the correct answer is C0.3 N–s.
