A car accelerates uniformly from rest to a speed of 7.6 m/s in 4.6 s. How far does the car travel in that time?

Physics

Answer:

The car will travel a distance of 17.45 meters.

Explanation:

Given:

Initial velocity (V_i) = 0

Final velocity (V_f) = 7.6 m/s

Time taken = 4.6 s

Acceleration = (Final velocity - Initial Velocity )/time

a=\frac{(V_f-Vi)}{t}= \frac{7.6-0}{4.6}=1.65\ ms^-2

We have to calculate total distance traveled by the car.

Let the distance traveled be 'd'

Equation of motion:

d=V_i(t)+\frac{at^2}{2}

Plugging the values.

⇒d=V_i(t)+\frac{at^2}{2}

⇒d=0+\frac{1.65*(4.6)^2}{2}

⇒d=17.45\ m

The car will travel a distance of 17.45 meters for the above case.

Calculate the Force required to give a bullet of mass 50 g an acceleration of 300 m/s2
NNADVOKAT [17]

Answer:

<h3>The answer is 15 N</h3>

Explanation:

The force acting on an object can be found by using the formula

<h3>Force = mass × acceleration</h3>

From the question

mass = 50 g = 0.05 kg

acceleration = 300 m/s²

We have

force = 0.05 × 300

We have the final answer as

<h3>15 N</h3>

Hope this helps you

The whale shark is the largest of all fish and can have the mass of three adult
ch4aika [34]

Answer:

m = 20,000 kg

Explanation:

Force, F=2.5\times 10^4\ N

Acceleration of the shark, a=1.25\ m/s^2

It is required to find the mass of the shark. Let m is the mass. Using second law of motion to find it as follows :

F = ma

Putting the value of F and a to find m

m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20,000\ kg

So, the shark's mass is 20,000 kg.

If you are traveling around a curve at a constant speed will your velocity change?
marta [7]

Velocity means [ (speed) and (direction) ].

If you're traveling around a curve, then your direction is
always changing.  So your velocity is always changing,
even if your speed isn't.
