It will move in the direction you pushed it, but it will go at a certain velocity
Explanation:
1. W = F x D
F = W/D
F = 120/6 = 20Newton
2. P. E = mgh
P. E = 1.5x10x2 = 30Joules
3. It means that the energy the body possesses at that point is 20Joules
The speed of the ball after one second is obtained as 9.8 m/s.
<h3>What is the speed after 1 second?</h3>
We know that since the ball dropped from a height, its initial velocity is zero.
Thus we have;
u = 0 m/s
v = ???
g = 9,8 m/s²
t = 1sec
Given that;
v = u + at
v = at
v = 9,8 m/s² * 1sec
v = 9.8 m/s

V= fx lambda
lambda, or wavelength= v/f
