Answer:
a) 30 degree
Explanation:
As we know that time of flight of the projectile depends on the the vertical component of the velocity always
It is given as
now we know that
so we will have
since we know that two projectiles are projected at same speed but different angles
so smaller the angle will take smaller time
so it would be 30 degree projectile which will take smaller time
89 degrees Fahrenheit would be 31.7 degrees Celsius!
Answer:
Velocity 
V = Q + 3Rt²
at t = 0, 
= Q + 3r(0) ==> Q
at t = T, 
= Q + 3rT²
Work done (W) = ΔKE = 
W = ![\frac{1}{2} m[(Q + 3RT^{2})^{2} - Q^{2}]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20m%5B%28Q%20%2B%203RT%5E%7B2%7D%29%5E%7B2%7D%20-%20Q%5E%7B2%7D%5D)
W = 
[Q² + 9R²T⁴ + 2Q(3RT²) - Q²]
W = (9R²T⁴ + 6QRT²)
