Answer:

v = 6.95 m/s

Explanation:

Given that,

A diver is on a board 1.80 m above  the water, s = 1.8 m

The initial speed of the diver, u = 3.62 m/s

Let v is the speed with which she hit the water. It will move under the action of gravity. Using the equation of motion as follows :

v^2-u^2=2gs\\\\v=\sqrt{u^2+2gs} \\\\v=\sqrt{(3.62)^2+2(9.8)(1.8)} \\\\v=6.95\ m/s

So, she will hit the water with a speed of 6.95 m/s.

!!HELP HELP!!
borishaifa [10]

Answer:

7.5s

Explanation:

Given parameters:

Velocity  = 30m/s

Deceleration  = 4m/s²

Unknown:

Time it takes for the car to come to complete rest  = ?

Solution:

 To solve this problem, we use the kinematics expression below:

        v  = u + at

 Since this is a deceleration

         v  = u - at

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time taken

         v - u  = -at

         0  - 30  = -4 x t

              -30  = -4t

               t  = 7.5s

An object accelerates downward at a constant rate of 3.75 m/s2 while completely submerged in water. Neglect the viscosity (fluid
guajiro [1.7K]

Answer:

Do = density of obect      Dw = density of water

Weight of object = V g Do

Weight of water = V g Dw

F = m a = V Do a = V g Do - V g Dw

Acceleration of object = mass * force on object

Do (g - a) = Dw g

Do = Dw ( 1 / (1 - a / g) = 1000 * 1 / (1 - 3.75 / 9.80)  kg/m^3

Do = 1441 kg / m^3

If no acceleration then density of object = density of water
