Answer:
about 4.097 seconds
Step-by-step explanation:
The vertical velocity is ...
(35 m/s)sin(35°) ≈ 20.075 m/s
When the projectile reaches the level from which it was launched (ground level), its final velocity will be the opposite of its initial velocity. Thus, the change in velocity is ...
-20.075 -(20.075) = -40.150 . . . . m/s
The acceleration is provided by gravity, which is -9.8 m/s², so the time required is ...
t = Δv/a = (-40.150 m/s)/(9.8 m/s²) ≈ 4.097 s
Answer:
Equation of circle is
None of the options is correct
Step-by-step explanation:
Given: Graph
To find: equation of circle
Solution:
A circle is a locus of all points that are at a fixed distance (radius) from a fixed point (centre).
From the graph,
centre (a, b) =
radius (r) = 4 units
Equation of circle is of form
