It's D
Explanation:
Sorry if im wrong, correct me in comments and tell them actual answer if I'm wrong.
Temperature increase, increases the kinetic energy of the molecules. Increase in temperature is an increase in energy level so, the rate of the reaction increases, motion of the particles increase. This means the particles move faster, collide more often with each other and collide with more energy.
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
