D2x/dt2=-g (which we'll approximate as a constant -32ft/s^2)
d2x/dt2=-32 integrating we get:
dx/dt=-32t+C, where C is the initial velocity which we are told is 128ft/s so
dx/dt=-32t+128, integrating again we get:
h(t)=-16t^2+128t+C, where C is the initial height of the object..which we are told is 136 ft so
h(t)=-16t^2+128t+136 if we factor the first two terms we get:
h=-16(t^2-8t)+136

<u>To find the density:</u>
⇒ must find the relationship between the density, mass, and volume
⇒
<u>Let's examine the information given:</u>
- weight: 1890g
- dimensions: 8cm * 5cm* 5cm
<u>Let's first find the volume:</u>
⇒ the volume is the dimensions multiplied together
<u>LEt's calculate the density now:</u>
<u>Answer:</u> The density of the copper is <u>9.45g/cm^3</u> or <u>Choice (A)</u>
<u></u>
Hope that helps!
