Answer:
2632 foot-pound
Explanation:
Work done: Work is said to be done when ever a force moves a body through a given distance. The S.I unit of force is Newton (N).
From the question,
The expression for work done is given as,
W = Fdcos∅......................... Equation 1
Where W = work done, F = force, d = distance, ∅ = angle between the force and the horizontal.
Given: F = 32 lbs, d = 90 feet, ∅ = 24°
substitute into equation 1
W = 32×90×cos24
W = 2880(0.914)
W = 2632.32
W = 2632 foot-pound

Answer:
Explanation:
Let the velocity of projection be V .
component of velocity in vertically downward direction = v cos 44.1
component of velocity in horizontal direction = v sin 44.1
s = ut + 1/2 gt²
611 = v cos 44.1 x 5.4 + 1/2 x 9.8 x 5.4²
= 611 = 3.88 v + 142.88
v = 120.65 m /s
b )
horizontal component of velocity of projectile = v sin 44 .1 = 120.65 sin44.1
= 83.96 m /s
horizontal displacement = 83.96 x 5.4 = 453.38 m
c ) horizontal component will remain unchanged so horizontal component
= v sin 44 .1 = 120.65 sin44.1
= 83.96 m /s
d ) velocity of projectile just before striking the ground
v = u + gt
= v cos 44.1 + 9.8 x 5.4
= 120.65 xcos 44.1 + 9.8 x 5.4
= 86.79 + 52.92
= 139.71 m /s
