. A little car has a maximum acceleration of 2.57 m/s2. What is the new maximum acceleration of the little car if it tows anothe
valkas [14]

Answer:

a'=1.285\ m/s^2

Explanation:

Let m be the mass of a little car and m' be the mass of another car.

We know that,

Force = mass × acceleration

ATQ,

m × a = 2m × a'

a = 2 × a'

a'=\dfrac{a}{2}\\\\a'=\dfrac{2.57}{2}\\\\a'=1.285\ m/s^2

So, the acceleration of another little car is equal to 1.285\ m/s^2.

A Formula One race car with mass 770.0 kg is speeding through a course in Monaco and enters a circular turn at 235.0 km/h in the
Marat540 [252]

Answer:

Explanation:

Given

mass of first car m_1=770 kg

speed =235 km/h\approx 65.27 m/s

radius of first turn=125 m

And Angular momentum is given by =mvr

Angular momentum of first car

L_1=770\times 65.27\times 125=6282,237.5 N-m/s

v_2=190\approx 52.77 m/s

r_2=100m

similarly L_2=770\times 52.77\times 100=4063290 N-m/s

\frac{L_1}{L_2}=\frac{r_1v_1}{r_2v_2}=\frac{125\times 65.27}{100\times 52.77}=1.546

Thus angular momentum of first car is 1.54 times of second one

Extend the life of your __________ by avoiding fast starts, stops and sharp turns.
skelet666 [1.2K]

Answer:

Tires.

Explanation:

There are the few steps which are discussed below should be taken to increase or extend the life of tires.

(1) Avoid fast starts: Fast start of the vehicle will increase the pressure on the tires due to the friction between the tires and the road will decrease the life of tires.

(2)  Avoid fast stop: Fast stop of the vehicle will also increase the pressure on the tires due to the friction between the tires and the road will decrease the life of tires.

(3) Avoid sharp turns: The alignment of the wheels and tires are in such a way that they work properly when vehicle is drive in a straight path but sharp turn will increase the uneven pressure on the tires will lead to decrease the life of tires.

Therefore, the life of tires can be extend by avoiding all the above mention actions such as fast stop, start and sharp turns.

When work is done on an object, where does the energy used to do the work go?
borishaifa [10]
-- If the work is done to make the object move faster, then
the work done becomes kinetic energy of the object.

-- If work is done on the object but it doesn't move any faster,
then there must be friction holding it back.  In that case, the work
that's done just to keep the object moving becomes heat, in the
places where the friction acts on it.
