Answer:
The work done by the drag force is given by 29.96 J
Explanation:
Given :
Thrust force 
N
Displacement 
m
Mass of rocket 
Kg
From work energy theorem,
Where 
thrust work 
gravitational work
After cutoff kinetic energy is converted into potential energy,
Put value of KE
Work done by drag force is given by,
J
Therefore, the work done by the drag force is given by 29.96 J
A is the answer for the problem
Answer:
Europium has a bright shiny surface. it's steel grey and has a melting point of 826 degree Celsius and a boiling point of about 1,489 degree Celsius.
Explanation:
the density is 5.24 grams per cubic centimeter.
m = mass held by mr. Z above his head = 200 kg
g = acceleration due to gravity = 9.8 m/s²
F = force applied by mr. Z to hold the mass
Using equilibrium of force , force equation is given as
F = mg
F = (200) (9.8)
F = 1960 N
Since the mass is not moved,
d = displacement of the mass = 0 m
we know that , work done is given as
W = F d
inserting the values
W = (1960) (0)
W = 0 J
Car B, Car C, And Car E Are either speeding up or slowing down
