A racing car has a mass of 750 kg. It undergoes an acceleration of 4.00 m/s2. What is the net force acting on the car?

Physics
1 answer:
navik [9.2K]2 years ago
3 0

Answer:

<h2>3000 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 750 × 4 = 3000

We have the final answer as

<h3>3000 N</h3>

Hope this helps you

Given a constant acceleration and assuming linear motion, derive equations for velocity and position of a body with respect to t
uysha [10]

Answer:

v = at + u

x = ut+\frac{1}{2}at^{2}+x_{0}

Explanation:

acceleration, a = constant

As we know that acceleration is the rate of change of velocity

a=\frac{dv}{dt}

dv=adt

integrate on both sides

\int dv=\int adt

v = at + u

Where, u is the integrating constant and here it is equal to the initial velocity

Now we know that the rate of change of displacement is called velocity

v = \frac{dx}{dt}

dx=vdt=(u+at) dt

Integrate on both sides

\int dx=\int (u+at) dt

x = ut+\frac{1}{2}at^{2}+x_{0}

where, xo is the integrating constant which is initial position of the particle.

An underwater scuba diver sees the Sun at an apparent angle of 43.0° above the horizontal. What is the actual elevation angle of
Inessa05 [86]

Answer:

The actual elevation angle is 12.87 degrees

Explanation:

In the attachment you can clearly see the situation. The angle of elevation as seen for the scuba diver is shown in magenta, we conclude that \theta_2=90-43=47.

Using Snell's Law we can write:

n_1\sin(\theta_1)=n_2\sin(\theta_2)

\implies \sin(\theta_1)=\frac{n_2}{n_1}\sin(\theta_2),

Let's approximate the index of refraction of the air (medium 1 in the picture) to 1.

We thus have:

\sin(\theta_1)=n_2\sin(\theta_2)=1.333\sin(47)

\implies\theta_1=\arcsin[n_2\sin(\theta_2)]=\arcsin[1.333\sin(47)]\approx 77.13. Calling \alpha the actual angle of elevation, we get from the picture that \alpha=90-77.13=12.97

A student measured the mass of ice in a glass container with a tight lid. He allowed the ice to melt, and then found the mass of
vfiekz [6]

Answer:

The liquid formed from a melted solid has the same mass as the solid has.

Explanation:

As long as no water can escape, the mass of the ice before melting must equal the mass of the liquid water after.
