Answer: 495.05 m
Explanation:
Given:
Initial velocity of the bullet, u = 1000 m/s, mass of the bullet, m = 10 g, mass of the wooden block, M = 1000 g,
From the swinging of the wooden block just after the collision with the bullet to its maximum height, using conservation law of mechanical energy we have that,
1/2(m+M) = (m+M)gh
Where h = the vertical height of the block in the direction will the block swing, and g = acceleration due to gravity = 10
=> v=
Using the conservation law of linear momentum,
mu = (m+M)v
mu = (m+M) (where v=)
=>h = *
h=

the answer is B! it would continue to expand.....just took the test XD
Calorimeters can be improved by impeding the loss of heat to the surroundings. A few things can improve this:
better insulation
less surface area to the surroundings
accurate heating
better stirring/mixing mechanism
