A drag racer can travel a displacement of 120m in 5.00s starting from rest. Calculate the acceleration of the drag racer. Can you calculate the final momentum of the car?
x = 0 + 0 + (1/2) a t^2
120 = (1/2) a (25)
240/25 = a
m v = m a t
so no. I do not know m
To calculate the acceleration of the drag racer, you can use the equation:
acceleration = (final velocity - initial velocity) / (time)
In this case, the drag racer starts from rest, so its initial velocity is 0. The displacement of 120m is not needed for calculating acceleration.
acceleration = (final velocity - 0) / (5.00s)
To calculate the final velocity, you can use the equation:
displacement = (initial velocity * time) + (0.5 * acceleration * time^2)
Since the drag racer starts from rest, the equation simplifies to:
displacement = 0.5 * acceleration * time^2
120m = 0.5 * acceleration * (5s)^2
Now, you can solve this equation to find the value of acceleration:
acceleration = (2 * displacement) / (time^2)
acceleration = (2 * 120m) / (5s)^2
acceleration ≈ 9.6 m/s^2
So, the acceleration of the drag racer is approximately 9.6 m/s^2.
To calculate the final momentum of the car, you need to know its mass and final velocity. However, since the mass of the drag racer is not given, we cannot provide an exact answer.
