Wending your way through this question and the list of choices
is like running through a corn-maze on a moonless night with
your eyes closed.
Work = (force) x (distance)
Keeping with the units used In the question ...
Work = (90 pounds) x (4 feet) = 360 foot-pounds .
If you want the work expressed in joules, then you need to convert
pounds and feet to newtons and meters.
(90 pounds) x (4.448 newtons/pound) = 400.32 Newtons
(4 feet) x (1 meter / 3.28084 feet) = 1.219 meters
Work = (force) x (distance)
= (400.32 newtons) x (1.219 meters) = 488.1 joules .

Answer:
69.42 m
Explanation:
From the question given above, the following data were obtained:
Initial velocity (vᵢ ) = 4.9 m/s
Acceleration (a) = 4.2 m/s²
Time (t) = 4.7 s
Displacement (Δx) =?
Thus, we can obtain the displacement by using the following formula:
Δx = vᵢt + ½at²
Δx = (4.9 × 4.7) + (½ × 4.2 × 4.7²)
Δx = 23.03 + (2.1 × 22.09)
Δx = 23.03 + 46.389
Δx = 69.419 ≈ 69.42 m
Thus, the distance travelled is 69.42 m
Answer:
His third law states that for every action or force in nature there is an equal and opposite reaction.

Answer:
"The weight of an empty bottle is 10N...Calculate the mass of the empty bottle."
w=Weight; m=Mass; g=Gravity
w=mg
w/g=m
10/9.81=m
1.019368kg = m
