Calculate the impulse (in kgm/s) received by a football when it's kicked in a kickoff. The ball has a mass of 0.27 kg and travels a horizontal distance of 68 m. The ball is kicked at an angle q of 20.5 with the horizontal and spends 2.276 seconds in the air.

Impulse experienced by the ball = 8.61 kgm/s

Explanation:

Impulse is given as change in momentum according to Newton's second law of motion

Impulse = mv (assuming the ball goes to rest after being kicked)

Range of a projectile is given as

R = uₓt

uₓ = horizontal component of the velocity = u cos(θ) = u cos 20.5° = 0.9367 u

t = time of flight, given in the question as 2.276 s

R = 68 m

68 = 0.9367 u × 2.276 = 2.132 u

u = 31.9 m/s

Impulse = mv = 0.27 × 31.9 = 8.61 kgm/s

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

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.
