Acar moving at a velocity of 25 m/s, accelerates at a rate of 6 m/s find its velocity after 3s

The answer would be:

Here is why:

To determine what the final velocity is, we can do this by using the kinematics formula:

Where:

Vf = final velocity

Vi = initial velocity

a = acceleration

t = time

In this case, the following are your given:

Vf = unknown

Vi = 25 m/s

a = 6 m/s²

t = 3 s

So just plug that in the equation and solve:

So the answer is 43m/s

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
