A bullet with mass m=5.21 g is moving horizontally with a speed v=560 m/swhen it strikes a block of wood with mass M=14.8 kg (initially at rest). The bullet embeds itself in the block.
(a)What is the speed of the bullet-block combination immediately after the collision?
m/s ( ± 0.002 m/s)
(b)What is the impulse exerted on the block?
kg m/s ( ± 0.02 kg m/s)
