A rock drops from a height of 60m. how long does it take for it to hit the ground?
laila [671]

To solve for the time an object takes to hit the ground, the equation

<em>y</em> <em>= y₀ + v₀t + ½gt²</em>, or just <em>0 = y₀ +½gt²</em> since there is no initial velocity and the final y position is 0 (since it is on the ground). Therefore, <em>t = (−2y₀/g)^½.</em>

(-2*60/-9.8)^½ = 3.50 seconds.

<u>Step-by-step explanation</u>

Given that the next model of the sports car will cost 5.2% less than the current model.

decrease in price=41000-38868=2132

There is a $2132 decrease in prize of the sports car.
