A 1423-kg car is moving along a level highway with a speed of 26.4 m/s. The driver takes the foot off the accelerator and the ca

Leona [35]

Answer:

Final speed, v = 28.81 m/s

Explanation:

Given that,

Mass of the car, m = 1423 kg

Initial speed of the car, u = 26.4 m/s

Force experience by the car, F = 901 N

Distance, d = 106 m

To find,

The speed of the car after traveling this distance.

Solution,

The force experienced by a car is equal to the product of mass and acceleration.

$F=ma$

$a=\dfrac{F}{m}$

$a=\dfrac{901}{1423}$

$a=0.63\ m/s^2$

Let v is the final speed of the car. Using third equation of motion to find it as :

$v^2-u^2=2ad$

$v^2=2ad+u^2$

$v^2=2\times 0.63\times 106+(26.4)^2$

v = 28.81 m/s

So, the final speed of the car is 28.81 m/s.

A 25 N force stretches a spring 0.280 m. What was the spring constant?

soldi70 [24.7K]

Answer:

the spring constant is -89.2857 n/m

Explanation:

The computation of the spring constant is shown below:

As we know that

Force in newtons = Spring constant × amount of extension

F = -k × x

where

F = 25 N

And, x = 0.280m

So, the spring constant would 2

= 25N ÷ 0.280 m

= -89.2857 n/m

Hence the spring constant is -89.2857 n/m
