Harry and Cassie wanted to conduct an experiment to see how many licks it takes to get to the center of a tootsie roll pop. Belo
w is their procedure and above are the results.
1. Obtain test subject. 2. Obtain unwrapped tootsie roll pop. 3. Test subject places tootsie roll pop in center of tongue and drags it to the tip. This is considered one lick. 4. Test subject swallows. 5. Before licking again, the test subject rotates the tootsie roll pop slightly with each new lick to make sure that the entire pop obtains adequate licking surface area. 6. Test subject licks while keeping track of all licks until the tootsie roll is encountered. What is wrong with this experiment?

Answer:
h≅ 58 m
Explanation:
GIVEN:
mass of rocket M= 62,000 kg
fuel consumption rate = 150 kg/s
velocity of exhaust gases v= 6000 m/s
Now thrust = rate of fuel consumption×velocity of exhaust gases
=6000 × 150 = 900000 N
now to need calculate time t = amount of fuel consumed÷ rate
= 744/150= 4.96 sec
applying newton's law
M×a= thrust - Mg
62000 a=900000- 62000×9.8
acceleration a= 4.71 m/s^2
its height after 744 kg of its total fuel load has been consumed
h= 58.012 m
h≅ 58 m
