Trained dolphins are capable of a vertical leap of 7.0 m straight up from the surface of the water-an impressive feat.Suppose yo
u could train a dolphin to launch itself out of the water at this same speed but at an angle. What maximum horizontal range could the dolphin achieve?
1 answer:
Answer:
Explanation:
Maximum height reached by Dolphins is given as
now we know that
now the formula of range is given as
now we know that for maximum range the angle should be 45 degree
so we will have

Explanation:
When physical pendulum is a system of rod and sphere then we will have
so we will have
so we will have
since mass of ball is much higher than the mass of rod
so we have
now when we use the rod as physical pendulum then we have
M = 0
so we have
so its time period is given as
Answer:
time =20s
Explanation:
Average speed = Distance/time
time = Distance / Average speed
Where Distance = 100meters and speed =5m/s
So,
time = 100m/5m/s
time =20s
