A wooden block has a mass of 45 kg and a specific heat of 1,700 J/(kg oC). Find the change in thermal energy of the block as it warms from 15 oC to 25 oC Please help me, I really need it.

How are momentum and impulse related? impulse is a whim to do something, while momentum keeps it going impulse is another name fore instantaneous momentum the impulse acting on and object is equal to the change of momentum it causes. the impulse that acts on and object is the momentum that results.
