Best ResponseYou've already chosen the best response.1dw:1350213752879:dw here h is slightly greater than the previous one thats why the ans will be 0.16 approx.

Best ResponseYou've already chosen the best response.0yes :) so i got the answer as 0.03j not 0.01 can u chck where iwent wrong

Best ResponseYou've already chosen the best response.0Δh = 5√2  5 = 2.07 cm = 0.0207 m g = 9.81 m/s² m = 0.150 kg Hence gain = 0.03 J

Best ResponseYou've already chosen the best response.0The collision is perfectly elastic and, without sliding, the block turns about the corner as shown. The block is able to reach the position as shown in the image. 25% of the kinetic energy of the ball is transferred to the block. Calculate 1. the kinetic enrgy of the balll just before it strikes the block
