The spring constant of the spring if it would compress by 1 m to stop the ore car is 340,350.4 N/m.
<h3>
Potential energy of the car</h3>
The potential energy of the car is calculated as follows;
P.E = mgh
where;
- h is the vertical height of the incline
sin (10) = h/L
h = L x sin(10)
P.E = mgLsin(10)
P.E = 2000 x 9.8 x 50 x sin(10)
P.E = 170,175.21
<h3>Conservation of energy</h3>
The potential energy of the car at the top of the incline will be converted to the elastic potential energy spring at the bottom of the incline.
P.E = U = ¹/₂kx²
k = (2U)/x²
k = (2 x 170,175.2)/(1)²
k = 340,350.4 N/m

Answer:
Stooping more Quickly
Explanation: Stooping more quickly means that Motor cycles can easily bend and stop,this is due to it's design, Motor cycle have only two wheels,they contain just two tyres one in front and one at the back,they are not as firm on the ground when compared to other vehicles such Motor car. They have a lower weight which makes them easily bent or stopped once there's any barrier.
Answer:
Explanation:
Given that
Intensity I
Radius of earth,R = 6370 Km
We know that surface area of earth, A
As we know that pressure due to intensity given as
V =Velocity of light
We know that force F
F = P .A
b)Gravitational force F
So F
