How does Connecticut energy affect the stopping distance of a vehicle traveling at 30 mph compared to the same vehicle traveling

at 60 mph?

Formula for stopping distance can be calculated by

v_f^2 - v_i^2 = 2 a d

here

v_f = 0

d = \frac{v_f^2}{2a}

now we can see from above equation that stopping distance depends on square of the speed.

So as we can see that here 30 mph and 60 mph, if the speed is double then the stopping distance will become four times more.

An object accelerates 3.0 m/s2 when a force of 6.0 N is applied to it. What is the mass of the object?
makvit [3.9K]

Answer:

<h2>2 kg</h2>

Explanation:

The mass of the object can be found by using the formula

m =  \frac{f}{a}  \\

f is the force

a is the acceleration

From the question we have

m =  \frac{6}{3}  \\

We have the final answer as

<h3>2 kg</h3>

Hope this helps you

A 2100 kg car starts from rest and accelerates at a rate of 2.6 m/s2 for 4.0 s. Assume that the force acting to accelerate the c
Reika [66]
When the system is experiencing a uniformly accelerated motion, there are a set of equations to work from. In this case, work is energy which consist solely of kinetic energy. That is, 1/2*m*v2. First, let's find the final velocity.

a = (vf - v0)/t
2.6 = (vf - 0)/4
vf = 10.4 m/s

Then W = 1/2*(2100 kg)*(10.4 m/s)2
W = 113568 J = 113.57 kJ
