A raindrop (mass=1.00g) is travelling 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.

• Physics -

change in heat to glass= KE of the raindrop

but
changeinheat=.100*specificheatwater(deltaTemp)

solve for changeinTemp

b. same, except change the mass to .101kg
