The answer is B) i am 100% positive
Answer:
<h2>158,400 J</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 4500 × 35.2 = 158400
We have the final answer as
<h3>158,400 J</h3>
Hope this helps you
The formula for acceleration, or average acceleration, is a=(vf-vi) divided by (tf-ti) .
a= Acceleration (or average acceleration
vf= Final Velocity
vi= Initial Velocity
tf= Final Time
ti= Initial Time

In endothermic reactions energy in the form of heat is given
Answer:
7.01yard/sec
Explanation:
Given parameters:
Initial position = 50yard
Final position = 12yard
Time = 5.42s
Unknown:
Average speed of runner = ?
Solution:
To solve this problem;
Speed =
Distance covered = Initial position - final position = 50 - 12 = 38yards
So;
Speed =
= 7.01yard/sec
