Answer:
90°
Explanation:
This angle is the measured between the force applied and the displacement where the force vector and the displacement vector are on opposite direction.
The formula for work in this case is ;
W=F*d* cos ∅ where ;
F= force, d= distance and ∅ is the work angle
For minimum work ∅ = 90°
For maximum work ∅ = 0°
Answer:
Explanation:
Range= U²sin2theta/g
= 102²* sin (2*42)/9.8
= 1054.74m
Yes she will be abable to jump
The distance from the edge will be
(1054.74- 420)m
= 634.74m
