Given:
Mass of elephant = 5240 kg
The initial speed of the elephant = 4.55 m/s
Mass of the rubber ball, m, = 0.15 kg
Inital speed of the rubber ball, v = 7.81 m/s
On substitution in =
+
=
+
a) The negatıve sign shows that the ball bounces back in the direction opposite to the incident
b) it is clear that the velocity of the ball increases and therefore it is kinetic energy . The ball gains kinetic energy from the elephant.
Answer:
Power develop at 6000 ft = 100 - 18 = 82 hp
Given:
Power produced by the engine at sea level = 100 hp
Explanation:
For each 1000 ft rise above the sea level, the power loss of the engine is about 3%
Therefore,
1000 ft - 3% loss
6000 ft -
At 6000 ft, the power loss is 18% or 18 hp
Now,
Power develop at 6000 ft = Power at sea level - Power loss at 6000 ft
Power develop at 6000 ft = 100 - 18 = 82 hp
