Answer:
Explanation:
When two cars collide then the momentum of two cars will remains conserved
- Mass of two cars = 100 kg
-
Speed of car B = - 10 m/s
-
After collision the speed of car B = +8 m/s
By momentum conservation equation
My Anonymuos friend, I could not agree more with your statement.
Truer words have rarely if ever been expressed.
Explanation:
The magnitude of centripetal acceleration is:
a = v² / r
The velocity is:
v = d/t
v = 2 × 2π (5 m) / 60 s
v = 1.05 m/s
a = (1.05 m/s)² / (5 m)
a = 0.219 m/s²
The direction is towards the center. So at point A, the centripetal acceleration is 0.219 m/s² downward, and at point B, the centripetal acceleration is 0.219 m/s² upward.
