AI Thread Summary
To determine how much slope the car can move on, it's essential to calculate the thrust at the wheels, which is derived from engine torque, gear ratio, and rolling radius. The maximum force available at the wheels can be calculated using the formula F = mg sin(theta), where m is the total weight and theta is the slope angle. By testing various angles, one can find the maximum slope the car can ascend. Additionally, rearranging the formula to solve for theta using arcsin may be necessary, depending on the mathematical knowledge. Understanding these calculations is crucial for the car's design and performance.

ppl i am jus 14 and tryin to make a car
the amount of physics i no is a bit less
i started calculating
by assuming:-
car weight = 50kg
passenger weight 50 kg
propultion system weight =5okg
total weight =150 kg
speed 20km/h = 5.5m/s
i am taking =5 m/s approx
time taken= 10 sec
acceleration =0.5m/s2
force =150 x 0.5=75 Newton
energy =1875juoles = 1.875kj
power = 187.5 watt
my question is that **"how much slope can it move on??"**
coz i don't no cos tan sin

ppl reply i need ur help
 
Formatting and full comprehensive sentences are your friend.

You need to know the thrust at the wheels.

Found from engine torque * gear ratio * rolling radius.
This will give you the max force available at the wheels.

F = mg sin theta

Run for a range of theta, and you can find the max slope you can get up.
or rearrange or theta and work it out with arcsin (I don't know if you will have learned that at 14)

hey can u find it for me i am havin problem
 
I can't find it for you, I have told you how to find it though.

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}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
