its gona go really fast because of the wait and the speed its thrown at
A particle is moving along a projectile path where the initial height is 96 feet with an initial speed of 16 feet per second.
let's find the maximum height<span>of the particle
</span><span>s(t)=−16<span>t2</span>+16t+96</span><span>
</span><span>s(1/2)=−16(1/2<span>)2</span>+16(1/2)+96=−16(1/4)+8+96=−4+8+96=100
Therefore the answer is 100

Answer:
Hi
Explanation:
the dancers wish to increase their grip which takes advantage of the force of friction.
Answer:
312 kJ
Explanation:
The thermal energy contained in a cubic meter of air at room temperature (20 C) and one atmosphere (101 kPa) would be.
H = Cv * T + p * V
Being
Cv: specific heat of air at constant volme (0.72 kJ/(kg*K))
T: temperature in absolute scale (20C is 293 K)
Then:
H = 0.72 * 293 + 101 * 1 = 312 kJ
The only way to extract thermal energy from a body and turn it into useful work (such as charging a phone) is to exchange heat with it and a another colder body. So, with just the air at room temperature it is impossible to extract its heat energy.
