QUESTION 7 A bullet of mass 40.0 g moving with a speed of 249 m/s strikes a block of wood of mass 2.00 kg and becomes imbedded in it (stuck inside it). The block had been originally at rest and is free to move. What is the speed of the block and bullet immediately after the collision, in units of m/s? QUESTION 10 If an object is initially at rest and then 'explodes' into two separate pieces, what do we...
My answer is 4 Ns. The question is - A 0.4 kg ball hits the ground vertically at a speed of 6 m/s, bouncing back in the opposite direction at 4 m/s. Calculate the magnitude of the impulse provided by the ground to the ball. Am I right?
