do only10th one i got 9th one it is a force of 5N acts on a body for 2ms calculate the impulse if the mass of body is 5g calculate change of velocity
impulse = chnge in momentum & force = momentum / time ....force is given 5N and time is 2 milisecond( 2×10^-3 sec.) calculate impuse by multiplying them..then equate it with "mv".. mass is given thn claculate velocity
