A spacecraft of mass 10 tonnes requires an acceleration of 11ms-2 to reach a space station. What force must the rockets produce on the spacecraft?
Answers
Answer: Given:-
Mass=10tonnes (convert to kg)
=10000kg
Acceleration=11m/s²
Force=mass×acceleration
=10000×11
=110000N
Explanation:
Given :
Mass of the spacecraft = 10 tonnes
Acceleration = 11m/s^2
Required to find :
- Force required to be produced by the rocket on the spacecraft .
Units Conversion :
Before coming to the explanation and solution .
First it is necessary to convert some units from one unit to another .
Here,
We need to convert the mass from tonnes to kilograms .
To convert tonnes into kilograms we need to use an formula .
The formula is ,
So,
10 tonnes = ? kilograms
Explanation :
Here, in the question we are given with
- Mass
- Acceleration
We need to find the force required to be produced by the rocket on the spacecraft .
This can be founded by using the most familiar formula .
The formula is,
Here,
Using this we can find the force required .
Additional Information :
Actually , this force was been derived from the Newton's 2nd law of motion .
This formula is very useful in solving many numerical's in physics .
Now, let's crack the Numerical .
Solution :
Given values ,
❶. Mass of the spacecraft = 10 tonnes = 10,000 kgs
❷. Acceleration = 11m/s^2
Using the formula
Hence,
Now substitute the required values in the formula .
We get,
The S.I. unit of force is newton .
Similarly,
So,
Hence,
