I was asked this question in physics but was confused on the question when it asks what is the value of acceleration .. but in the problem it says the acceleration is constant.. If anyone can help me out that be great!! The catapult of the aircraft carrier...
Answer:
There is no conflict in asking for the (constant) value of the acceleration: a = V²/2x = [173*...

I have a calculus problem that asks me to find the velocity and acceleration of an elevator. When I find them both I get something like this: velocity: x=-2 y=1 x=-1 y=1 x=0 y=0 x=1 y=1 x=2 y=1 Acceleration: x=-2 y=0.032 x=-1 y=-0.5 x=0 y=0 x=1 y=0....
Answer:
The data seem to be describing an elevator as it goes up two floors, with a stop at the intermediate...

If we derive the function of a trajectory, we get velocity. If we derive that function, we get acceleration. What happens when we derive the function we have for acceleration? It seems like we would get the rate of change of accel./ time...ughhh? lol...

The technical term is 'jerk' (or jolt in the UK). It is used for elevators where it jolts people less...

I'm sorry I'm just in a hurry... 1. A car starts from rest and accelerates to a speed of 50 km/hr in 15 sec. What is its acceleration in km/sec^2? 2. A car is going 30 m/sec and has to stop for a dead pig in the road. What is its acceleration if it takes...
Answer:
1- a = dv / dt = 50km / 15 = 3.333km/s2 2- a = dv / dt = 30 / 25 = -1.2 m/s 3- e = 1/2 a * t^2 t^2 ...

Say I have one velocity a, and I want to go from another velocity b, how much acceleration do I need to apply? Is there a formula for this? The reason I ask is because I am making a speed control module in a simple 2d racing game, where I know what speed...
Answer:
You have : --------------------------------------… a = acceleration a = ( v sub b - v sub a ...

What is the acceleration during takeoff of a jumbo jet, with a mass of 33,000 kg when the thrust for each of its four engines is 30,000 N? A net force on to a 2 kg cart accelerates the cart at 6 m/s2. How much acceleration will the same net force produce...
Answer:
These are all just applications of F = ma In the first one F = sum of all forces = 30,000 * 4, rearrange...

A crate of mass 45.0 kg is being transported on the flatbed of a pickup truck. The coefficient of static friction between the crate and the truck's flatbed is 0.300, and the coefficient of kinetic friction is 0.250. The truck barely exceeds this acceleration...
