Answer:
H = 5 m
Explanation:
As the person leaves the slide horizontally so the time taken by the person to hit the water is given as
so we can find the vertical velocity by which person will hit the water using kinematics
now the speed of the person at the end of the slide is given as
now by energy conservation we can find the initial height
The humpback whale would migrate farther north in the summer because they have so much fat that the temperature needs to be a lot cooler for them to survive thus they move to cooler waters
U = 80mph = 35.76m/s
S = 0.8m
M = 3500kg
To find the deceleration, we use equation of motion to calculate that
V² = u² + 2as
But v = 0
0 = u² + 2as
-U² = 2as
a = -u² / 2s
a = -(35.76)² / (2 * 0.8)
a = 1278.78 / 1.6 = 799.24 m/s²
The force exerted on the truck during deceleration is equal to the summation of all the forces acting on the truck.
∑F = m. ⃗a
-F = 3500 * 799.24
F = -2797331.25N
F = -2797.33kN
F = -2.797MN.
This response suggests that she is most likely in the pre-operational stage of cognitive development. This answer based on the Piaget's 4 Stages of Cognitive Development. The preoperational stage is the second stage of Cognitive development where human's have not yet reach the logical thinking ability. However<span>, the human already can think of image and object.</span>
The reason why the moon can't be eclipsed when it's halfway between the nodes of the orbit because the moon's orbit is at it's maximum deviation, meaning that it is leaving it's course from the sun's path, which would make the shadow fall way below or above the moon. Because of that, the moon can't eclipsed.
