Calculating the Temperature Change of Water After a Raindrop Strike

[larry21]

A raindrop (mass=1.00g) is traveling at a speed of 40m/s when it hits the surface of 100g of water contained in a drinking glass. What is the change in temperature of the water in the glass if we assume that i)all the kinetic energy of the raindrop is converted to energy that changes the water's temperature, and ii)the water in the glass and the raindrop were at the same original temperature?

I found the kinetic energy of the raindrop, but I don't know what to do after that. Please help. Thanks.

You need the equation "heat lost by 1 g = heat gained by 100 g"
and the formula "heat gained or lost = m*C*ΔT"
