$5 \times 10^{- 3} N s$
$5.8 \times 10^{- 3} N s$
$5.8 \times 10^{3} N s$
$5 \times 10^{3} N s$

The correct answer is: $5 cross times 10 to the power of negative 3 end exponent N s$

$text Impulse end text equals open parentheses table attributes columnalign left end attributes row cell text Area of force - time graph end text end cell row cell text under the specified interval end text end cell end table close parentheses equals 1 half left parenthesis 800 plus 200 right parenthesis cross times 2 cross times 10 to the power of negative 6 end exponent plus 1 half cross times 800 cross times 10 cross times 10 to the power of negative 6 end exponent equals 5 cross times 10 to the power of negative 3 end exponent N minus s$

A steel ball of radius R = 20 cm and m = 2 kg is rotating about a horizontal diameter with angular speed w₀ = 50 rad/sec. This rotating ball is dropped on a rough horizontal floor and fall freely through a height h = 1.25 m. The coefficient of restitution is e = 1 and coefficient of friction between ball and floor is $mu equals 0.3$ . Then the distance in m between the point of first and second impact of the ball and floor is
