In an experiment to estimate the acceleration due to gravity, a student drops a ball at a distance of 1 m above the floor. His l

ab partner measures the time it takes to fall and obtains an estimate of 0.46 s.
(a) What do they estimate the acceleration due to gravity to be?
(b) Let s be the ball's position relative to the floor. Using the value of the acceleration due to gravity that they obtained, and assuming that the ball is released at t = 0. determines (in m) as a function of time.

Answer:

9.45179\ m/s^2

s=4.725895t^2

Explanation:

t = Time taken = 0.46

u = Initial velocity

v = Final velocity

s = Displacement = 1 m

a = Acceleration

s=ut+\frac{1}{2}at^2\\\Rightarrow 1=0\times 0.46+\frac{1}{2}\times a\times 0.46^2\\\Rightarrow a=\frac{1\times 2}{0.46^2}\\\Rightarrow a=9.45179\ m/s^2

The acceleration due to gravity is 9.45179 m/s²

s=ut+\frac{1}{2}at^2\\\Rightarrow s=\frac{1}{2}at^2\\\Rightarrow s=\dfrac{1}{2}9.45179t^2\\\Rightarrow s=4.725895t^2

The function is s=4.725895t^2

A speeding motorist traveling with velocity Vm is spotted by a police car. The police car is initially at rest, but the instant
Svetlanka [38]

Answer:

Explanation:

Given

Let us suppose police car and motorist travel in straight line  and police car catches motorist after s distance

Distance travel by motorist

s=v_mt----1

Distance traveled by Police car

s=ut+\frac{at^2}{2}

s=0+\frac{a_pt^2}{2}

s=\frac{a_pt^2}{2}----2

from 1 & 2 we get

t=\frac{2v_m}{a_p}

(a)Velocity of Police car after t sec

v=u+a_pt

v=0+a_p\times \frac{2v_m}{a_p}

v=2v_m

(b)time taken by police car is

t=\frac{2v_m}{a_p}

(c)Distance travel by police car=\frac{2v_m^2}{a_p}

Does the earths magnetic field change with time?
ZanzabumX [31]

Answer:

As per the fossil fuel records, magnetic field reversal does not impact living beings. It will take almost a century for the poles to complete the shift. Meanwhile, the earth is left with almost zero magnetic field.

A 56.6-kg crate rests on a level floor at a shipping dock. The coefficients of static and kinetic friction are 0.517 and 0.260,
kifflom [539]

Answer:

Explanation:

Magnitude of frictional force = μ mg

μ is either static or kinetic friction.

To start the crate moving , static friction is calculated .

a ) To start crate moving , force required = μ mg where μ is coefficient of static friction .

force required =.517 x 56.6  x 9.8 = 286.76  N .

b ) to  slide the crate across the dock at a constant speed , force required

= μ mg where μ is coefficient of kinetic  friction , where μ is kinetic friction

= .26 x 56.6  x 9.8 = 144.21 N .

A hazard sign has 3 identical
melomori [17]

Answer and Explanation: To know how much tape he will need, we have to calculate the perimeter of each parallelogram-shaped stripe.

Perimeter is the sum of all the sides of a figure.

For a parallelogram:

P = 2*length + 2*width

So, we need to determine width and length of the stripe.

Width is 3 inches. Length is the hypotenuse of the right triangle, whose sides are 6 and 18 inches. Then, length is

h=\sqrt{18^{2}+6^{2}}

h=\sqrt{360}

h = 19 in

Perimeter of the first stripe is

P = (2*19) + (2*3)

P = 44 inches

The hazard sign has 3 stripes. So total perimeter is

P_{t}= 44 + 44 + 44

P_{t}= 132 inches

To outline the parallelogram-shaped stripes, Charles need a total of 132 inches of tape. Since one roll has 144 inches, he will have enough tape to finish the job.
