Suppose the designers of the water slide want to adjust the height h above the water so that riders land twice as far away from the bottom of the slide. what would be the necessary height above the water?
a. 1.2 m
b. 1.8 m
c. 2.4 m
d. 3.0 m

option C

Explanation:

given,

Range is doubled

for range to be doubled height should become 4 times.

formula to calculate the horizontal range

          R = v T_{flight}

using equation of motion

now,

where, h is the height of the

Assuming the height be equal to 0.6 m

to calculate the new height

hence, the correct answer is option C

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

the inner core.

good luck: )
