A plane lands and comes to a complete stop through 180 m of runway with a deceleration of 6.25 m/s2 [N]. Determine the plane’s v elocity when it first touched the landing strip.
1 answer:
Answer:
47.43 m/s
Explanation:
Given that,
Final speed of a plane, v = 0
Distance, d = 180 m
Acceleration of the plane, a = -6.25 m/s² (deceleration )
We need to find the plane's velocity. Let it was u. So, using the third equation of kinematics as :
So, the plane's velocity when it first touched the landing strip is 47.43 m/s.

The higher the temperature the more kinetic energy there is going to be because the particals move faster
Answer:
The principle of work and kinetic energy (also known as the work-energy theorem) states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle.

Light bouncing or reflecting off an object in different ways.
I just took a quiz and this was the answer
(k12 answer)
Answer:
Exothermic because energy is a product
Explanation:
Since energy is a product, heat was released, meaning that the reaction is exothermic.
It's the movement of a object along the circumference of a circle or the rotation along a circular path.
