Abaseball has a mass of 0.15 kg and radius 3.7 cm. in a baseball game, a pitcher throws the ball with a substantial spin so that it moves with an angular speed of 45 rad/s and a linear speed of 42 m/s. assuming the baseball to be a uniform solid sphere, determine the rotational and translational kinetic energies of the ball in joules.

Explanation:

Given

mass of baseball

radius of ball

angular speed of ball

linear speed of ball

Transnational Kinetic Energy is given by

Considering the ball as solid sphere its moment of inertia is given by  

Rotational Kinetic Energy

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper

the total distance traveled by the car is

30km + 49km = 79 km .
