Projectile Is shot upward from the surface of Earth with an initial velocity of 136 meters per second. Use the position

Anna007 [38]

Answer:

$v(3\,s) = 106.6\,\frac{ft}{s}$ , $v(15\,s) = -11\,\frac{ft}{s}$

Step-by-step explanation:

The velocity function of the projectile is obtained by deriving the position function:

$v(t) = -9.8\cdot t + 136$

Now, the velocities after 3 and 15 seconds are, respectively:

$v(3\,s) = -9.8\cdot (3) + 136$

$v(3\,s) = 106.6\,\frac{ft}{s}$

$v(15\,s) = -9.8\cdot (15) + 136$

$v(15\,s) = -11\,\frac{ft}{s}$

To start with, convert 52 feet into metres
1 Feet= 0.3048
52 feet= ?
The number of meters= 52*0.3048
The number of meters= 15.8496 metres

The school need to add a further 1.8496 metres
