Assume it is in uniform deceleration.
u=25
v=0
s=x
a=?
t=12
v=u+at
0=25+a(12)
a=-2.08(3sig fig)
decelerarion of 2.08 ms^(-2)/
acceleration=-2.08ms^(-2)
Answer:
large
Explanation:
the harder you pluck the louder it gets
Answer:
V (initial vertical velocity) = 45.4 sin 31.2 = 23.52 m/s
1/2 m V^2 = m g h conservation of energy
h = V^2 / (2 g) = 23.52^2 / 19.6 = 28.2 m max height
Check:
t = 28.2 / 9.8 = 2.88 sec time to reach max height
h = 23.52 * 2.88 - 1/2 g 2.88^2 = 27.1 m
