Answer:
Ice and Rock
Explanation:
There's also dust and sand mixed up
acceleration= change in velocity/ time taken
initial velocity=(36×1000m)/3600
= 10m/s
final velocity= (54×1000m)/3600
=15m/s
change in velocity= final - initial
=15 - 10
=5m/s
time taken = 5s
acceleration=15/5
=3metre per second square
Answer:
3.2 kg
Explanation:
x = Stretched length
k = Spring constant
c = Damping constant
Force
For critical damping
The mass that would produce critical damping is 3.2 kg
Answer:
in an accident, when the body collides with the air bags, the collision time of impact between the two bodies will increase due to the presence of air bags in the car. Larger is the impact time smaller is the transformation of energy between the body and air bag. That is why air bags greatly reduce the chance of injury in a car accident.
