Answer:
yes. everything around you is matter including you!
Answer:
The centripetal on the car will become 4 times when the velocity gets twice.
Explanation:
As we know that centripetal force on the car of mass m and moving with constant speed v given as
m=mass
v=velocity
r=radius of the circular arc
We are assuming that the mass of the both the car is same.
If the velocity of the car gets twice 2 v
The new centripetal force on the car
Therefore we can say that centripetal on the car will become 4 times when the velocity gets twice.
That information only tells me your average speed during that hour.
No wait ! I take that back.
Covering 40 miles in a single hour on a bicycle is a world-class
achievement. So that information also tells me that you are in
unbelievably superb physical condition.
Answer:
4.3 m/s
Explanation:
Using conservation of momentum, assume that the collision is elastic and that the 3.0 g ball stuck with the carton
3.0 g = 3 / 1000 = 0.003 kg = m₁
40 g = 40 / 1000 = 0.04 kg = m₂, u₂ = 0 since the body is stationary and v = 0.3m/s
m₁u₁ + m₂u₂ = v ( m₁ + m₂)
0.003 u₁ = 0.30 ( 0.003 + 0.04) = 0.0129
u₁ = 0.0129 / 0.003 = 4.3 m/s
Answer:
Explanation:
Given that force changes with distance. From Physics we remember that work can be defined by the following integral equation:
(1)
Where:
- Force.
- Work.
- Distance.
If we know that , then the work of the nonlinear spring is:
(2)
If we know that and , then the amount of work done by stretching the spring a distance is:
