The cycle of cellular respiration and photosynthesis are important for the life of plants because cellular respiration uses one of the products of photosynthesis (oxygen), and uses it as one of the reactants along with glucose to produce carbon dioxide. These two cycles help maintain a balance for our atmosphere, even though pollution and other factors have disrupted this balance. Hope this helps! :)
The position of the mass is given by (in cm):

The velocity is the derivative of the position:

Substituting t=0.40 s, we can find the velocity at this time:
A gravity and or D angular momentum
Answer:
Explanation:
Given
initial speed of Launch
=53.7 m/s
Range of Projectile =Maximum height of Projectile
Range is given by R
Maximum height is given by 



![\frac{u^2\sin \theta }{g}\cdot \left [ 2\cos \theta -\frac{1}{2}\right ]=0](https://tex.z-dn.net/?f=%5Cfrac%7Bu%5E2%5Csin%20%5Ctheta%20%7D%7Bg%7D%5Ccdot%20%5Cleft%20%5B%202%5Ccos%20%5Ctheta%20-%5Cfrac%7B1%7D%7B2%7D%5Cright%20%5D%3D0)
as u cannot be zero therefore
