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:

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

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

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

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

The experimental probability that Pedro will hit a hole in one at the golf course is 2/5. If Pedro goes golfing 40 times in a ye

Sati [7]

I'm pretty sure you would need to multiply 2/5 by 40.

So, if you multiply 2/5 by 40, you need to turn 40 into a fraction with 1 being the denominator.

2/5 x 40/1 = 80/5

Since the product is an improper fraction, you would simplify it to a whole number.

80/5 = 16.

He can expect to hit it 16 times to get a hole in one.

I hope I am right and have a great day.
