Impulse Momentum Wkst 3 Key Impulsive force model worksheet 3 conservation of momentum 1 answer key By the end of this section you will be able to do the following. Momentum is the product of mass and velocity which makes the two quantities inversely proportional. The result found by my method is wrong, instead the solution to this question involves the use of Weight of the combined system which is downward thus acting opposite to the Force(with which the ground resists penetration).When a 150 kg cannon and cart recoils at 15 ms at what velocity would a. V(initial) = v one the other hand v(final) = 0 īy solving for "t" and then substituting "t" in the Force(with which the ground resists penetration) equation we get the final result of the force. I solved the first part by finding the velocity of the combined system to be "x"īut i am unable to solve the 2nd part of the question.įorce (with which the ground resists penetration) = (m+M)x/tĪs the force is constant thus the acceleration would also be constant, thus :Īverage velocity = /2 (for constant acceleration) average velocity= (v+u)/2 Once you read the question (attached) you'll notice that there are two different parts of the question, the first one asks to find the combined velocity of the system after collision while the 2nd one uses the result of the first part and states to find the force.
