dw:1350213752879:dw here h is slightly greater than the previous one thats why the ans will be 0.16 approx.

hmm...do we actually consider the height from the horizontal to cntre of gravity or as a whole?

i dont knw how to solve it, coz the answer doesnt equal to 0.01 j, maybe theres a problem in the question. anyway thanks for helping

Gain in potential energy is m g Δh , where Δh is gain in altitude of the centre of mass of the body.

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

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

The 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
