Calculate Velocity of a Car from Rest
What is the velocity of a car that starts from rest and accelerates uniformly at the rate of 5 m/s^2 for 5 seconds?
Calculate the final velocity of the car.
Final Velocity Calculation:
The velocity of a car that starts from rest and accelerates uniformly at the rate of 5 m/s^2 for 5 seconds is 25 m/s.
When a car starts from rest and accelerates uniformly at the rate of 5 m/s^2 for 5 seconds, we can calculate the final velocity using the equation of motion:
v = u + at
where:
v is the final velocity,
u is the initial velocity (which is 0 for a car starting from rest),
a is the acceleration (5 m/s^2 in this case), and
t is the time (5 seconds).
Substitute the values into the equation:
v = 0 + (5 m/s^2 * 5 s) = 25 m/s
Therefore, the velocity of the car after 5 seconds of accelerating at 5 m/s^2 is 25 m/s.
