The united states and south korean soccer teams are playing in the first round of the world cup. an american kicks the ball, giving it an initial velocity of 3.6 m/s. the ball rolls a distance of 5.0 m and is then intercepted by a south korean player. if the ball accelerates at −0.50 m/s2 while rolling along the grass, find its velocity at the time of interception.

v=2.82 m/s

Explanation:

Given

initial velocity of ball(u)=3.6 m/s

ball rolls a distance(s) of 5 m

ball acceleration

Velocity of ball when it is intercepted by Korean player

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
