Solution :
Key Idea: The product of the force and the time interval is called the impulse of the force. If a constant force \[\overset{\to }{\mathop{\mathbf{F}}}\,\] is applied on a body for a short interval of time \[\Delta t\] then the impulse of this force is\[\overset{\to }{\mathop{\mathbf{F}}}\,\times \Delta t\]. Let \[m\] be the mass of the body.You need to login to perform this action.
