We know, work done = Force * displacement
Here, w = 12,000 J
f = 300 N
Substitute their values into the expression:
12,000 = 300 * d
d = 12,000 / 300
d = 120/3
d = 40 m
In short, Your Answer would be 40 meters
Hope this helps!
--vertical from ground to top--
v^2 = u^2 + 2as
with v= 0, a=g, s=u^2/(-2g)
g on the moon is 1/6
u is equal, then it goes 6 times higher on the moon.
v = u + at
with v= 0, a=g, t = u/(-g)
g on the moon is 1/6
u is equal, then it takes 6 times longer on the moon.
--horizontal--
s = vt , v is equal
t on the moon is 6 time longer
it moves 6 times farer on the moon
A factor of 50dB = a factor of 10^(50/10) = 10^5 = a factor of <em>100,000</em> .
Explanation:
Given that,
An object in free fall will fall d feet in t seconds, where d and t are related by the algebraic model as :
..........(1)
(a) We need to find the time taken by the object to fall 1148 ft. Put this in equation (1) as :
t = 8.47 seconds
(b) If the object is in free fall for 18.5 sec after it is dropped, then the height of the object is given by :
d = 5476 ft
Hence, this is the required solution.
the answer is A i took a test
