Abaseball pitcher throws a baseball horizontally at a linear speed of 49.4 m/s. before being caught, the baseball travels a horizontal distance of 24.7 m and rotates through an angle of 52.7 rad. the baseball has a radius of 3.43 cm and is rotating about an axis as it travels, much like the earth does. what is the tangential speed of a point on the "equator" of the baseball?

Explanation:

As we know that ball travels horizontal distance of 24.7 m with uniform speed 49.4 m/s

so we will have

now in the same time ball is turned by angle

now we know that

now the tangential speed of a point at equator is given as

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.
