If a ball is thrown into the air with a velocity of 45 ft/s, its height in feet after t seconds is given by y=45t-15t2. Find the
Morgarella [4.7K]

Given that a ball is thrown into the air and its height in feet after t seconds is given by y = 45t - 15t²,  the instantaneous velocity when t=4 is -75ft/s.

<h3>What is the instantaneous velocity when t=4?</h3>

Given that;

  • Initial velocity = 45ft/s
  • Height in feet after t seconds is given by y = 45t - 15t²
  • Instantaneous velocity = ?

First, we determine the derivative of y = 45t - 15t²

y' = (1)45 - (2)15t

y' = 45 - 30t

We substitute in t = 4

y' = 45 - 30t

y' = 45 - 30(4)

y' = 45 - 120

y' = -75ft/s

Given that a ball is thrown into the air and its height in feet after t seconds is given by y = 45t - 15t²,  the instantaneous velocity when t=4 is -75ft/s.

A monkey weighs 6.00 x 102 N and swings from vine to vine. As the monkey grabs a new vine, both vines make an angle of 35.0° wit
natka813 [3]

To solve this problem we will apply the considerations of equilibrium on a body, we will decompose the tensions into their respective components and apply the sum of forces and solving equations for the given system.

According to the graph, the sum of the horizontal components would be

\sum T_x = 0

TSin35\° -TSin35\° = 0

0 = 0

The sum of the vertical components is

\sum T_y = 0

2TCos35\° - mg = 0

2TCos35\° = 600N

T = \frac{600N}{2Cos35\°}

T = 366.2N

Therefore the net force on the new vine is 366.2N

just olya [345]

Answer:

C. 1.50×10¹¹ m

Explanation:

First, convert the time to seconds.

8 min × (60 s/min) + 20 s = 500 s

Distance = speed × time

d = (3×10⁸ m/s) (500 s)

d = 1.50×10¹¹ m
