The velocity of a car doubles over a short period of time. Which additional information is sufficient to determine the amount of

Rom4ik [11]

Answer:

Time and velocity

Explanation:

The time taken for the velocity to double is very important to find the amount of acceleration the car acquires.

Acceleration is the rate of change of velocity with time.

Acceleration = $\frac{v -u}{t}$

v is the initial velocity

u is the final velocity

t is the time taken

So, the velocity and time is needed to calculate the value of the acceleration the car undergoes.

Children slide down a frictionless water slide that ends at a height of 1.80 m above the pool. If a child starts from rest at po

Lerok [7]

Answer:

$h = 1.75 m$

Explanation:

As we know that height of the slide is given as

$h = 1.80 m$

so time taken by the child to hit the water from the slide is given as

$t = \sqrt{\frac{2h}{g}}$

now we will plug all data in it

$t = \sqrt{\frac{2(1.80)}{9.81}}$

$t = 0.605 s$

now we know that the horizontal distance moved by it is given as

$L = v_x t$

$3.55 = 0.605 v_x$

$v_x = 5.86 m/s$

now by energy conservation

$mgh = \frac{1}{2}mv^2$

so height of point A is given as

$h = \frac{v_x^2}{2g}$

$h = \frac{5.86^2}{2(9.81)}$

$h = 1.75 m$
