A ball is thrown upward. what is its initial vertical speed? the acceleration of gravity is 9.8 m/s 2 and maximum height is 4.1 m ,. neglect air resistance. answer in units of m/s
1 answer:
the question is missing another parameter. we need to know the time taken for the ball to come down. You can use the below formula to find the initial vertical speed.
S = 1/2at2 + ut
distance = 1/2 × acceleration × time2 + intial speed × time

Answer:
150 m
Explanation:
Given,
u=5m/s
a=2m/s2
t=10s
v=?
s=?
Now,
v=u+at
=5+2×10
=5+20
=25m/s
So,
s=u+v/2×t
=5+25/2×10
=30/2×10
=15×10
=150m
