A ball is thrown upward with an initial velocity of 60 mph. it is thrown from a height of 5 feet. what is the maximum height it
natima [27]

Answer:

h = 61.25 m

Step-by-step explanation:

It is given that,

The initial velocity of the ball, v = 60 m/s

It is thrown from a height of 5 feet, h_o=5\ ft

We need to find the maximum height it reaches. The height reached by the projectile as a function of time t is given by :

h=-16t^2+vt+h_0

Putting all the values,

h=-16t^2+60t+5 .....(1)

For maximum height, put

\dfrac{dh}{dt}=0\\\\\dfrac{-16t^2+60t+5}{dt}=0\\\\-32t+60=0\\\\t=\dfrac{-60}{-32}\\\\t=1.875\ s

Put t = 1.875 in equation (1)

h=-16(1.875)^2+60(1.875)+5\\\\h=61.25\ m

So, the maximum height reached by the ball is 61.25 m.

kipiarov [429]

Answer:

Based on this report, you can conclude that a total of ___11__ individuals participated in the research study .

Step-by-step explanation:

Given that a  research report describing the results from a repeated-measures study states:

The data show no significant difference between the two treatments, t(10) = 1.65, p > .05.

Since t(10) is given, we can conclude that degrees of freedo is 10

Hence sample size is 10+1 =11

Based on this report, you can conclude that a total of ___11__ individuals participated in the research study .
