Question

A block is thrown upwards with a kinetic energy 1 J. If it goes up to a maximum height of 1m, find m.

Answer 1

Answer:

using princile of energy conservation initial kinetic energy = final potential energy

 

thus

mgH = 1

m = 1/gH = 1/(10*1) = 0.1 kg

Answer 2

Answer:

answer is 0.1

Explanation:

using principle of energy conservation

initial Kinetic energy=Final potential energy

thus,

mgh=1

m=1/gh =1/(10*1)

=0.1
