Korolev's name became known in the West. I hope this helps.
Answer:
2621.25 meters
Explanation:
First, write down what we are given.
Initial velocity = 27.5 m/s
Final velocity = 42.4 m/s
Time = 75 seconds
We need to look at the kinematic equations and determine which one will be best. In this case, we need an equation with distance. I am going to use 
, but you can also use the other equation, 
We need to find acceleration. To find it, we need to use the formula for acceleration: 
. Plugging in values, 
Next, plug in what we know into the kinematics equation and solve for distance. 
Answer:
<h2>9.3kN</h2>
Explanation:
Step one:
given data
mass of bullet= 0.02kg
speed v=700m/s
time taken =1.5ms= 0.0015 seconds
Step two:
we know that from the first law
F=ma-----1 first law of motion
also, we know that
a=v/t----2
put a=v/t in equation 1 we have
F=mv/t
Step three:
substitute our given data to find force
F=0.02*700/0.0015
F=14/0.0015
F=9333.33N
F=9.3kN
<u>The average force exerted is 9.3kN</u>
Answer:
x₁ = 58.09 m
Explanation:
Displacement is calculated by finding the final distance away from a point then subtracting the initial distance.
Given that initial position of object is x=25.89 m
Displacement Δx=32.2 m
Final position x₁=?
Δx = x₁-x
32.2= x₁-25.89
32.2+25.89 = x₁
58.09 m =x₁
