Answer:
Soory
Explanation:
I really dont know but i will send you wait
Explanation:
Derived quantities are quantities dependent on fundamental quantities while derived units are the units of these quantities
the answer is true acceleration is the change in distance over time.
hope this helps
Answer:
25.2 m
Explanation:
The horizontal distance traveled s = v × t×cosθ and t = s / (v×cos θ)
The vertical distance traveled h = v × t ×sin θ - 1/2 × g × t^2
Substituting for t, h = s×tan θ- 1/2 × g × s^2 / (v cos θ)^2
Now, Solve for v^2 and get v^2 = g × s^2 ÷ [2 ×cos^2θ × (s×tan θ - h)]
And v^2 = 9.8×3600 / [2×0.535×(60×0.933 - 25] =1065 and v = 32.6 m/s
As a check from the first equation t = 60 / (32.6×0.731) = 2.52 sec
Horizontal distance traveled s = 32.6×cos 43°×2.52 =60 m
Height reached 2×g×h = (v×sin43°)^2
⇒and h = 25.2 m (using 2×g×h =v×y ^2)
Since maximum height is reached at the edge of the cliff the projectile
will not travel beyond the cliff
