A 970 kg car starts from rest on a horizontal roadway and accelerates eastward

Physics
1 answer:
a_sh-v [17]3 years ago
4 0

Answer: 4850N

Explanation:

Mass of car = 970 kg

Time = 5 s

Speed = 25 m/s

Average force exerted on the car = ?

Recall that Force is the product of the mass of an object and the acceleration by which it moves

i.e Force = mass x acceleration

(Since, acceleration is the rate of change of velocity or speed per unit time)

i.e Acceleration = Speed / Time

Acc = 25m/s / 5s

Acc = 5m/s^2

Average force = mass x acceleration

Avg force = 970 kg x 5m/s^2

= 4850N

Thus, the average force exerted on the car is 4850 Newton

A ray of light passes from air into carbon disulfide (n = 1.63) at an angle of 28.0 degrees to the normal. what is the refracted
Snezhnost [94]
We can solve the problem by using Snell's law, which states 
n_i \sin \theta_i = n_r \sin \theta_r
where
n_i is the refractive index of the first medium
\theta_i is the angle of incidence
n_r is the refractive index of the second medium
\theta_r is the angle of refraction

In our problem, n_i=1.00 (refractive index of air), \theta_i = 28.0^{\circ} and n_r=1.63 (refractive index of carbon disulfide), therefore we can re-arrange the previous equation to calculate the angle of refraction:
\sin \theta_r =  \frac{n_i}{n_r}  \sin \theta_r =  \frac{1.00}{1.63}  \sin 28.0^{\circ} = 0.288
From which we find
\theta_r = \arcsin (0.288)=16.7^{\circ}

Explain why it is better to use a cable with a low resistance than to use a cable with a high
blondinia [14]

Explanation:

The primary reason for this is efficiency. In most applications, a lower resistance means less power is converted to heat and lost to the surrounding environment and more of the supplied power gets to its intended destination.

1 ) when a ball is projected upwords its time of rising is ...............the time of falling .
balu736 [363]

Answer:

correct answer is C

Explanation:

In this exercise, you are asked to complete the sentences so that the sentence makes sense.

1) in projectile launching, the only force that acts is gravity in the vertical direction, so the time of going up is EQUAL to the time of going down

correct answer C

2) when a body falls freely, the acceleration is the ratio of gravity, therefore if it starts from rest, its height is

            y = v₀ t - ½ gt²

v₀ = 0

             y = -1/2 g t²

so the position is not proportional to the square of the time

correct answer is C

How does Newton's law of motion describe when and how objects move?
r-ruslan [8.4K]
Newton's laws of motion relate an object's motion to the forces acting on it. ... In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
