Hi there!
We can begin by deriving the equation for how long the ball takes to reach the bottom of the cliff.
There is NO initial vertical velocity, so:
Rearrange to solve for time:
Plug in the given height and acceleration due to gravity (g ≈ 9.8 m/s²)
Now, use the following for finding the HORIZONTAL distance using its horizontal velocity:
Answer : The specific heat of aluminum is,
Solution : Given,
Heat absorbs = 677 J
Mass of the substance = 10 g
Final temperature =
Initial temperature =
Formula used :
or,
Q = heat absorbs
m = mass of the substance
c = heat capacity of aluminium
= final temperature
= initial temperature
Now put all the given values in the above formula, we get the specific heat of aluminium.
Therefore, the specific heat of aluminum is,
