PtichkaEL [24]

Answer:

0.27m

Explanation:

To get the energy

Potential energy= Mgh

M is Mass

G is acceleration due to gravity

H is height..

M= 0.29kg, h= ?

P=0.759. g=9.8m/s

Therefore,

0.759=0.29×9.8×h

H= 0.759÷2.842

H= 0.27m

Murljashka [212]

Total displacement=6800m
Time=2h=7200s

$\\ \sf\longmapsto Avg\: Velocity=\dfrac{Total\: displacement}{Total\:time}$

$\\ \sf\longmapsto Avg\: Velocity=\dfrac{6800}{7200}$

$\\ \sf\longmapsto Avg\: Velocity=0.9420m/s$
