A 4 kg bowling ball is rolled down the bowling alley lane. The ball accelerates at 1.5 m/s2. If the force of sliding friction between the ball and the lane is 98 N, what was the force applied to the bowling ball?

Answer : The specific heat of metal is,

Explanation :

In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.

where,

= specific heat of metal = ?

= specific heat of water =

= mass of metal = 50 g

= mass of water = 100 g

= final temperature =

= initial temperature of metal =

= initial temperature of water =

Now put all the given values in the above formula, we get

Therefore, the specific heat of metal is,
