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 is
Solution
The impulsive force can be calculated using the formula:
Impulse = Force x Time
But we don't have the force. We can find it using Newton's second law:
Force = mass x acceleration
First, convert the mass from grams to kilograms because the standard unit of mass in physics is kilograms.
150 g = 0.15 kg
Then, substitute the mass and acceleration into the formula:
Force = 0.15 kg x 20 m/s² = 3 N
Now, we can find the impulse by substituting the force and time into the impulse formula:
Impulse = 3 N x 0.1 s = 0.3 Ns
So, the impulsive force is 0.3 Ns.
