A projectile is launched at ground level with an initial speed of 45.0 m/s at an angle of 30^o (30 degree) above the horizontal. It strikes a target above the ground 2.5 seconds later. What are the and distances from where the projectile was launched to where it lands

103.32 m

Explanation:

From the question, The distance from where the projectile was lunched to where its land is the range(R) of the projectile

R = (U²sin2Ф)/g Equation 1

Where U = initial velocity of the projectile, Ф = angle above the horizontal, g = acceleration due to gravity.

Given: U = 45 m/s, Ф = 30°

Constant: g = 9.8 m/s²

Substitute these values into equation 1

R = (45²sin30°)/9.8

R = 2025(0.5)/9.8

R = 103.32 m.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.
