Assume orange is going from left to right and apple is going from right to left 
If mv is the momentum of apple at angle θ to the x axis, 
In the x direction 
0.130*v cos θ = (0.170*1.23) -(0.130*1.08) 
0.130*v cos θ = 0.0687-------------------------2 

In the y direction 
0.130*v sin θ = (0.170*0.974) = 0.16558--------------1 

From 1 and 2 
tan θ = 2.41 

θ = 74.96º 
Substituting the value of θ in 
0.130*v cos θ = 0.0687 

v = 1.38 m/s

Two coconuts fall freely from rest at the same time, one from a tree twice as high as the other. If the coconut from the shorter
valentinak56 [21]

Wee can use here kinematics

as we know that

y = v*t + \frac{1}{2} at^2

for shorter tree we know that

y = 0 + \frac{1}{2}*9.8 * 2^2

y = 19.6 meter

now since we know that other tree is twice high

So height of other tree is y = 39.2 m

now again by above equation

y = v*t + \frac{1}{2} at^2

39.2 = 0 + \frac{1}{2}*9.8 * t^2

t = 2.83 s

so the time taken is 2.83 s

Most ocean waves obtain their energy and motion from _____. the moon's gravitational attraction the sun plate movement the wind
IrinaVladis [17]
Hello!

Most ocean waves obtain their energy and motion from the wind.

Ocean waves are surface waves that move across the surface of the ocean. When wind touches the surface of the water, there is friction in the contact zone. This friction causes a drag effect, that makes wrinkles on the surface of the water. As the wrinkles get bigger, they transform into full-blown waves, and the taller the wave, the more energy it can extract from the wind, making them even bigger and to move longer distances. 

Have a nice day!
