Question

Aball of mass 0.5 kg slows down from a speed of 5ms?
to that of 3ms! Calculate the change in kinetic
energy
of the ball
= 0.5 be
leilla​

Answer 1

M = 0.5 kg

u = 5 m/s

v = 3 m/s

Initial Kinetic Energy = ½ * 0.5 * 25 = 6.25 J

Final kinetic energy = ½ * 0.5 * 9 = 2.25

Change = Final - Initial

= 6.25 - 2.25 = 4.24 J

Answer 2

Answer:

volcano is an opening in the Earth's crust through which lava volcanic ash, and gases escape beneath a volcano liquid magma dissolved containing dissolved gases can rises through crack in the earth's crust As the magma rises pressure decreases allowing the gases to from bubbles thanks
