A ball A of mass 1 kg moving at a speed of

5 \mathrm{~m} / \mathrm{s}

strikes tangentially another ball B initially at rest. The ball A then moves at right angles to its initial direction at a speed of

4 \mathrm{~m} / \mathrm{s}

. If the collision is elastic, the mass (in kg ) of ball B and its momentum after collision (in

\mathrm{kg}-\mathrm{m} / \mathrm{s}

) respectively are (approximately)

Options

A1.2 and 1.8
B2.2 and 3.3
C4.6 and 6.4
D6.2 and 9.1

Correct answer

C. 4.6 and 6.4

Step-by-step solution
