because the mass of the copper is higher than the mass of the gold.
Explanation:
Answer:
A
Explanation:
Becuse its complete number
At the player's maximum height, their velocity is 0. Recall that
![{v_f}^2-{v_i}^2=2a\Delta y](https://tex.z-dn.net/?f=%7Bv_f%7D%5E2-%7Bv_i%7D%5E2%3D2a%5CDelta%20y)
which tells us the player's initial velocity
is
![0^2-{v_i}^2=-2g(0.65\,\mathrm m)\implies v_i=3.6\dfrac{\rm m}{\rm s}](https://tex.z-dn.net/?f=0%5E2-%7Bv_i%7D%5E2%3D-2g%280.65%5C%2C%5Cmathrm%20m%29%5Cimplies%20v_i%3D3.6%5Cdfrac%7B%5Crm%20m%7D%7B%5Crm%20s%7D)
The player's height at time
is given by
![y=v_it-\dfrac g2t^2](https://tex.z-dn.net/?f=y%3Dv_it-%5Cdfrac%20g2t%5E2)
so we find their airtime to be
![0.65\,\mathrm m=\left(3.6\dfrac{\rm m}{\rm s}\right)t-\dfrac g2t^2\implies t=0.36\,\mathrm s](https://tex.z-dn.net/?f=0.65%5C%2C%5Cmathrm%20m%3D%5Cleft%283.6%5Cdfrac%7B%5Crm%20m%7D%7B%5Crm%20s%7D%5Cright%29t-%5Cdfrac%20g2t%5E2%5Cimplies%20t%3D0.36%5C%2C%5Cmathrm%20s)
