A stone is thrown with an initial upward velocity of 7.0 m/s and experiences negligible air resistance. If we take upward as the positive direction, what is the velocity of the stone after 0.50 s?
 
  A) 2.1 m/s
  B) 4.9 m/s
  C) -2.1 m/s
  D) -4.9 m/s
  E) 0.00 m/s

Question 2

A 40.0-g block of ice at -15.00C is dropped into a calorimeter (of negligible heat capacity) containing water at 15.00C. When equilibrium is reached, the final temperature is 8.00C.
 
  How much water did the calorimeter contain initially? The specific heat of ice is 2090 J/kg  K, that of water is 4186 J/kg  K, and the latent heat of fusion of water is 33.5  104 J/kg. A) 302 g
  B) 345 g
  C) 405 g
  D) 546 g
  E) 634 g

Did you know?

As many as 28% of hospitalized patients requiring mechanical ventilators to help them breathe (for more than 48 hours) will develop ventilator-associated pneumonia. Current therapy involves intravenous antibiotics, but new antibiotics that can be inhaled (and more directly treat the infection) are being developed.

Did you know?

Allergies play a major part in the health of children. The most prevalent childhood allergies are milk, egg, soy, wheat, peanuts, tree nuts, and seafood.

Did you know?

The eye muscles are the most active muscles in the whole body. The external muscles that move the eyes are the strongest muscles in the human body for the job they have to do. They are 100 times more powerful than they need to be.

Did you know?

Although not all of the following muscle groups are commonly used, intramuscular injections may be given into the abdominals, biceps, calves, deltoids, gluteals, laterals, pectorals, quadriceps, trapezoids, and triceps.

Did you know?

Many supplement containers do not even contain what their labels say. There are many documented reports of products containing much less, or more, that what is listed on their labels. They may also contain undisclosed prescription drugs and even contaminants.
