Answer:
R^3 = GM / ω^2
R^3 = (6.67 * 10^-11) * (5.98 * 10^24) / (0.00007272)^2
R^3 = 7.54 * 10^22
R = 42,251,269
R = 4.225 * 10^7 m
4.225 * 10^7
Explanation:
Answer:
-4714.28N
Explanation:
Given
- Mass of person, m= 55 kg
- Car speed initially ,u =30
- Car speed finally, v=0(car comes to a halt)
- Duration for the car to come halt,t=0.35 sec
This question is based on the concept of Impulse
Impulse is the force acting in a time interval(usually very short)
it is equal to force multiplied with time and also equal to change in momentum of body
⇒
Therefore the seat belt exerts a force of -4718.28N on the person
The<u> negative sign</u> signifies that seat belt exerts force in opposite direction of Force
