If you go from 58 m/s to 7 m/s in 26 seconds, what is your acceleration? Were you speeding up or slowing down?

m = 1 gram

Explanation:

Given that,

Heat, Q = 84 J

The temperature increases from 10°C to 30°C.

We need to find maximum number of grams of liquid water. We know that the heat required is given by :

c is specific heat of water, c = 4,200 J/kg°C

Use the above formula to find m. So,

or

m = 1 gram

So, the required mass is 1 gram.
