Maximum acceleration of 1500 kg car on concrete surface?

AI Thread Summary
The maximum acceleration of a 1500 kg car on a concrete surface, with two-thirds of its weight on the drive wheels and a static friction coefficient of 1, is calculated to be 6.53 m/s². This calculation is based on the formula F = ma, where the force is derived from the weight distribution. While the presence of a backward frictional force on the non-drive wheels could affect real-world performance, it can be ignored if the mass of the wheels is negligible. The provided answer of 6.53 m/s² is confirmed as correct. Understanding these dynamics is crucial for accurate vehicle performance assessments.

Homework Statement


Two-thirds of the weight of a 1500 kg car rests on the drive wheels. What is the maximum acceleration of this car on a concrete surface?

μs = 1

F = ma[/B]

The Attempt at a Solution



The answer I got is 6.53 m/s^2 , but I want to make sure the answer is correct.[/B]

Yes, your answer (2g/3) is correct.

In reality, there will also be a backwards frictional force on the other (non-drive) wheels to get them rotating, but if the mass of the wheels are negligible then this can be ignored.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
