Question
A force of 50 dynes is acted on a body of mass 5 g. which is at rest for an interval of 3 sec, then impulse is -
Solution
To find the impulse, we can use the formula:
Impulse = Force x Time
Given: Force = 50 dynes Time = 3 sec
First, we need to convert the mass from grams to kilograms: Mass = 5 g = 5/1000 kg = 0.005 kg
Next, we need to find the acceleration using Newton's second law: Force = Mass x Acceleration Acceleration = Force / Mass Acceleration = 50 dynes / 0.005 kg = 10000 m/s^2
Now, we can calculate the impulse: Impulse = Force x Time Impulse = 50 dynes x 3 sec = 150 dynes·sec
Therefore, the impulse acting on the body is 150 dynes·sec.
