Answer:
V = 25.3 , θf = 36.7° below the horizontal
Explanation:
Given Vo = 22m/s , θ = 23°
Vx = VoCosθ
Vy = VoSinθ – gt
t = total time of flight
To calculate the ideal mechanical advantage of a lever divide the input arm by the output arm.
Mechanical advantage is the amount by which a machine can multiply an input force, calculated by dividing output Force in newtons by input force in newtons, while the ideal mechanical advantage is the mechanical advantage of a machine that has no friction, calculated by dividing the input distance by the output distance.
The answer is C. If the box is accelerating, that means that the amount of force you are exerting is greater than the force of the box.
Answer:
The force is
