David drops a soccer ball off a building. The building is 75 meters tall.
Nezavi [6.7K]

a) 70.1 m

The ball is moving by uniformly accelerated motion, with constant acceleration g=9.8 m/s^2 (acceleration due to gravity) towards the ground. The height of the ball at time t is given by the equation

h(t)=h_0 - \frac{1}{2}gt^2

where h_0 = 75 m is the height of the ball at time t=0. Substituting t=1 s, we can find the height of the ball 1 seconds after it has been dropped:

h(1 s)=75 m - \frac{1}{2}(9.8 m/s^2)(1 s)^2=70.1 m

b) 3.9 s

We can still use the same equation we used in the previous part of the problem:

h(t)=h_0 - \frac{1}{2}gt^2

This time, we want to find the time t at which the ball hits the ground, which means the time t at which h(t)=0. So we have

0=h_0 - \frac{1}{2}gt^2

And solving for t we find

t=\sqrt{\frac{2h_0}{g}}=\sqrt{\frac{2(75 m)}{9.8 m/s^2}}=3.9 s

X – 3 = 8 <br> pls give step by step explanation.
inn [45]

Answer:

x = 11

Step-by-step explanation:

x - 3 = 8  add 3 to both sides

x + 3  -3 = 8 + 3 the 3s cancel each other out, 8 + 3 = 11

x = 11

a gym has 275 members 40% are bronze members 28% are silver members the rest are good work out the gold members
statuscvo [17]
STEP 1:
Find % of gold members. Subtract the known % of bronze and silver members from 100%.

x= percent of gold members

x= 100% - (40% +28%)
x= 100% - 68%
x= 32% percent of gold members


STEP 2:
Find number of gold members. Multiply % of gold members by the total numbers of members (275).

x= # of gold members

x= 275 * 32%
x= 275 * 0.32
x= 88 gold members

Hope this helps! :)

What is the value of a^3, if a =7
alekssr [168]
Ok so remember
x^n means x times itself n times
example
x^2=x times x
x^4=x times x times x times x
so

a^3
a=7
a^3=a times itself 3 times therefor
a^3=a times a times a
subsitute 7 for a
7^3=7 times 7 times 7
7^3=343
