Use the kinematic equation: Vf=Vi+at
Then plug;
Vi=14 m/s
a=5 m/s²
t=20 s. Therefore;
Vf=14+(5*20)
Vf=114 m/s.
Because maybe the ball was going downwards or he was getting ready to catch the ball. one of those 2.
Answer:
it looks like they are embracing eachother, so i would say the bottom right corner
Explanation:
Answer:
<em>The volume is increased in a ratio of 64/27</em>
Explanation:
<u>The Volume of a Sphere
</u>
The volume of a sphere of radius r is given by:
If the radius was changed to r', the new volume would be:
Dividing the latter equation by the first one:
Simplifying:
Or, equivalently:
Since r':r = 4:3, thus:
The volume is increased in a ratio of 64/27
Answer;
= 520.833 m
Explanation and solution;
Assuming D is at 25 m/s; T's acc = 2.4 m/s2
let time be t and distance be d
for D,
25 × t = d
t = d/25 ----(1)
for T,
u=0
s= ut + 0.5 at^2
d = 0 + 0.5 × 2.4 × t^2
d = 1.2 t^2 ----(2)
(1) sub into (2)
d = 1.2 × [d/25]^2
d = 0.00192 d^2
d = 520.833 m
