if a 1100 lb motorcycle(w/2 passengers)is doing 40mph,how long will take to come to a complete stop?
Nobody knows because you did not give us the coefficient of friction between the tires and the road or the de-acceleration some other way.
if a 1100 lb motorcycle(w/2 passengers)is doing 40mph,how long will take to come to a complete stop? this is happening with a full brake lock up.skid!in a stright line.
To determine the time it takes for a motorcycle to come to a complete stop, we need to consider several factors, including the braking force and the friction between the motorcycle's tires and the road surface.
First, let's assume that the motorcycle is traveling on a flat, dry road, and it comes to a complete stop through braking only (without any external forces or factors). In this scenario, we can apply the principle of physics that relates force, mass, and acceleration: F = m * a, where F is the net force, m is the mass, and a is the acceleration.
To calculate the net force required to stop the motorcycle, we need to determine the deceleration. Deceleration is the negative acceleration that opposes the direction of motion, causing the motorcycle to stop. In this case, we want the motorcycle to stop from 40 mph (which needs to be converted to units of meters per second).
To convert mph to meters per second, we multiply by a conversion factor: 1 mph = 0.447 m/s. So, 40 mph equals 17.88 m/s (approximately).
Next, we can calculate the deceleration. The deceleration can be determined using the formula: a = (vf - vi) / t, where vf is the final velocity, vi is the initial velocity, and t is the time taken.
Since we want the motorcycle to stop, the final velocity (vf) is 0 m/s. The initial velocity (vi) is 17.88 m/s (which was obtained from converting 40 mph). Plugging these values into the formula, we have: 0 = (17.88 - 0) / t.
Simplifying the equation, we get: 17.88 / t = 0.
To solve for t, we divide both sides of the equation by 17.88: t = 17.88 / 0.
However, we cannot divide by zero, which means that the motorcycle will never come to a complete stop solely through braking. In reality, there will always be external factors such as air resistance, rolling resistance, and other forces that can prevent the motorcycle from coming to an absolute stop in an infinitely small time frame.
Overall, the time it would take for a 1100 lb motorcycle (with two passengers) traveling at 40 mph to come to a complete stop will depend on additional factors like the motorcycle's braking system, road conditions, and other external forces.
