Answer: M = 1797.75 kg
Explanation:
given parameters are;
speed V = 26.7 M/S.
momentum P = 4.8×10^4 KGM/S.
What was the mass of the V. A-3?
Momentum P is the product of mass and velocity. That is, P = MV
Substitute V and P into the formula
4.8×10^4 = 26.7 × M
Make M the subject of formula
M = 4.8×10^4/ 26.7
M = 1797.75 kg
Therefore, the mass of the V. A-3 was 1797.75 kg
I hope its helps you . you can also write 1.44×10^3 it will be better
Answer:
3 m/s
Explanation:
Average Speed = 
Plug in the numbers, it will be (6m + 3m) divided by (2s + 1s), which is 9m/3s, which equals to 3m/s.
Answer:
Part a)

Part b)

Part c)

Explanation:
Part a)
As we know that force on the passenger while moving in circle is given as

now variation in force is given as

here speed is constant
Part b)
Now if the variation in force is required such that r is constant then we will have

so we have

Part c)
As we know that time period of the circular motion is given as

so here if radius is constant then variation in time period is given as
