You release a ball from rest attached to a string as shown in Figure A. The ball swings freely, and at the bottom of its circular path it strikes a stationary block. The block slides to the left with a speed of 4ms, and the ball bounces back to the right. To what maximum ￼￼￼height does the ball swing back as shown in Figure B? Assume no mechanical energy is lost at any time. (The string’s length is 7 m. The ball’s mass is 1kg, the block’s mass is 4kg, ignore the mass of the string.)
If needed, g=10ms2.
Maximum Height in Figure B =- unanswered meters
