0.10\,\text{kg}

ball moving to the right with a speed of

5.0\,\text{m}\,\text{s}^{-1}

strikes a stationary block S that has an unknown mass

M

. The impact is perfectly elastic. Immediately after the collision the ball is observed to reverse its direction and move to the left with a speed of

2.0\,\text{m}\,\text{s}^{-1}

. Answer the following parts. a. (a) Determine the speed of block S immediately after the collision. b. (b) Calculate the value of the mass

M

of block S.
