The only one way that heat can move is: From
higher temperature
to lower temperature, never the other way.
Examples:
-- When you put an ice cube into a glass of warm soda, heat never moves
out
of the ice cube into the soda, making the soda warmer.</span>
-- When you mix cold water with warm water, heat never moves out of the
cold water into the warm water, causing ice to appear and the warm water
to get warmer.
-- When you blow your breath across a spoonful of hot soup, the soup
never draws heat out of your breath, chilling your breath and boiling the
soup on the spoon.
-- When you step into a warm steaming bubble bath, heat never moves
from your body into the hot bath, causing your tootsies to shiver and the
bath to get even hotter.
The momentum of the 155 kg car afterwards is 469.7 kg m/s to the right
Explanation:
We can solve the problem by using the law of conservation of momentum: the total momentum of the system is conserved before and after the collision, so we can write:
where:
is the mass of the bumper car
is the initial velocity of the bumper car (we take the right as positive direction)
is the final velocity of the bumper car
is the mass of the second bumper car
is the initial velocity of the second car (moving to the left)
is the final velocity of the second car
Solving for ,
where the positive sign means the direction is to the right.
And now we can find the momentum of the 155 kg afterwards, which is
(to the right)
