Answer:
The minimum time, t = 21.11 m
Explanation:
Given,
The maximum distance between the Earth and Mars, d = 780,000,000 km
The maximum distance between the Earth and Mars, d = 780,000,000 km
The speed of the light, c = 300,000 km/s
The distance and speed of the object is related using the formula,
v = d / t
t = d / v
The minimum time it takes for data transmission is when the distance between the Mars and the Earth is at minimum.
Therefore,
t = 380,000,000 km / 300,000 km/s
= 1266.67 s
= 21.11 minutes
Hence, the minimum time it takes for data transmitted by the Mars Surveyor to reach earth, t = 21.11 minutes
Assuming that the can is motionless, we can then assume that the vertical component of T = mg and that Fe = the horizontal component of T.
<span> Since T itself is larger than it's vertical or horizontal components separately, then T is greater than all the forces.</span>
Answer:
The final velocity of the object is,
= 27 m/s
Explanation:
Given,
The acceleration of the object, a = 1000 m/s²
The initial displacement of the object,
= 0 m
The final displacement of the object,
= 0.75 m
The initial velocity of the object will be,
= o m/s
The final velocity of the object,
= ?
The average velocity of the object,
v = (
-
)/ t
= 0.75 / t
The acceleration is given by the relation
a = v / t
1000 m/s² = 0.75 / t²
t² = 7.5 x 10⁻⁴
t = 0.027 s
Using the I equation of motion,
= u + at
Substituting the values
= 0 + 1000 x 0.027
= 27 m/s
Hence, the final velocity of the object is,
= 27 m/s
