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) Three hole punch and either a layered plastic or paper
B) Identify the lengths involved ,
Length of input arm / length of output arm = L1/ L2
Explanation:
<u>a) Materials involved includes :</u>
Three hole punch and either a layered plastic or paper
Identify the forces acting on the three-hole punch which are Input and output forces
Identify the points where they act
<u>B) procedures involved </u>
The mechanical advantage = output force / input force
step one: Identify the lengths involved
assuming no friction or relatively small friction \
mechanical advantage can be calculated as : Length of input arm / length of output arm = L1/ L2
