Explanation:
Initial speed of the rocket, u = 0
Acceleration of the rocket,
Time taken, t = 3.39 s
Let v is the final velocity of the rocket when it runs out of fuels. Using the equation of kinematics as :
Let x is the initial position of the rocket. Using third equation of kinematics as :
Let is the position at the maximum height. Again using equation of motion as :
Now and v and u will interchange
x = 524.14 meters
Hence, this is the required solution.
Answer:
Explanation:
The concept of elastic and inelastic demand is applied.
for an elastic demand, the elasticity must be greater than 1 and for an Inelastic demand, the elasticity must be less than 1.
The steps and appropriate calculation is as shown in the attached file.
