Answer:
The acceleration of the plane is -2.14 m/s² ⇒ 2nd answer
Explanation:
<u><em>Acceleration</em></u> is the rate of change of velocity
The unit for acceleration is meters per second square
The rule of the acceleration is: →
where a is the acceleration, u is the initial velocity, v is the final velocity
and t is the time
An airplane traveling 245 m/s east experiences turbulence so the pilot
slows down to 230 m/s
It takes the pilot 7 seconds to slow down to this speed
We need to find the acceleration of the plane
Lets use the rule above
→ u = 245 m/s , v = 230 m/s , t = 7 seconds
→
→
→ The acceleration is -2.14 m/s²
<em>The acceleration of the plane is -2.14 m/s²</em>
Answer: A
Explanation:
Object 2:
Mass: 6kg
Height: 3m
Acceleration due to gravity: 9.8
The formula is Where;
= Gravitational potential energy
m = mass
g = acceleration due to gravity
h = height
