When a particular race car can cover a quarter mile track 402 m in 6.00 s starting from a standstill Assuming the acceleration is constant how many g's does the driver experience?

Formula for distance traveled with constant acceleration is:
S = v0t + at2 / 2.
Knowing the distance, time and that initial velocity is zero:
S = at2 / 2,
a = 2S / t2, or numerically:
a = 804 / 36 = 22.33 m/s2
Expressing that in terms of g(=9.81 m/s2):
a = 2.28 g

What do you think will happen to the cart's acceleration when it is pulled with a constant net force?
The cart's acceleration will be directly proportional to the net force applied to it. If the force remains constant, the acceleration will also remain constant, assuming no other external factors are affecting the cart's motion.
How does mass affect accelaration?
From the formula force = mass x acceleration, if there is more mass, there will be less acceleration. Assuming the force doesn't also change.From the formula force = mass x acceleration, if there is more mass, there will be less acceleration.

What is the relationship of acceleration to gravity?
Gravity produces acceleration on an object, assuming that no other force acts on the object.
Why is acceleration zero when the body is moving with a constant velocity?
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
What is the acceleration of falling bodies?
Near Earth's surface, the acceleration is about 9.8 meters/second2, assuming air resistance can be neglected.
What happens to the acceleration if the force applied is increased three times?
Assuming the mass remains constant, the acceleration will be tripled as well.
What is the greatest acceleration a runner can muster if the friction between her shoes and the pavement is 72 percent of her weight?
72% of the gravitational acceleration - assuming a flat surface.
Is the acceleration of a projectile equal to zero when it reaches the top of its trajectory?
No, assuming no air resistance, there will be a constant downward acceleration of 9.8 meters per second square (assuming standard gravity). The vertical component of the velocity will be zero at the top of the trajectory.
Can an object's rate of acceleration decrease and its speed increase at the same time?
Yes, assuming the object's rate of acceleration remains positive during the time it is decreasing.
Why car still accelerates after slowing down?
Acceleration is a change in velocity. Assuming a constant direction, if you're speeding up that is positive acceleration. If you are slowing down, that's negative acceleration. Either way you are accelerating.
If a rock is dropped and it's speed increases from 0 to 4.9 in about 3 seconds. what is the acceleration?
Assuming that your units of velocity are in units/second Acceleration = (velocity 2 - velocity 1) / time Acceleration = (4.9 - 0) / 3 Acceleration =1.63 *With correct significant figures the answer is 2
What is the decrease of speed called in physics?
Any change of velocity, including a decrease of speed, is described and measured as acceleration. Assuming the velocity and acceleration vectors point in the same direction, then in the case of decreasing speed, the magnitude of the acceleration is a negative value. Negative acceleration is often called deceleration, but that is just a special case of acceleration.
