<span>a planes engines are designed to move it forward at high speed. That makes air flow rapidly over the </span>wings<span>, which throw the air down toward the </span>ground<span>, generating an upward force called </span>lift<span> that overcomes the </span>plane's<span> weight and holds it in the sky. ... The </span>wings<span> force the air downward and that pushes the </span>plane<span> upward</span>
Answer:
38.87 m/s
Explanation:
Given that the ball is dropped from a height = 77 m
u = 0 m/s
s = 77 m
a = g = 9.81 m/s²
Applying the expression as:

Applying values as:

<u>The speed with which the ball hit the ground = 38.87 m/s</u>
2 miles away from home. 12/6 gives you 6 miles per half hour and then you take 8-6 and get 2 miles. So Jamal is 2 miles away from home.
B. The amount of work done by the worker on the wheelbarrow is 250 J.
<h3>Work done by the worker</h3>
The amount of work done by the worker on the wheelbarrow is calculated as follows;
W = Fd
where;
- F is applied force
- d is displacement
W = 50 x 5
W = 250 J
Thus, the amount of work done by the worker on the wheelbarrow is 250 J.
