What is the initial velocity of the car?
The speed of the vehicle before deceleration or braking.
You and your bike have a combined mass of 80kg. How much braking force has to be applied to slow you from a velocity of 5ms to a complete stop in 2s?
To calculate the braking force, we need to determine the deceleration first. Using the formula: final velocity = initial velocity + (acceleration * time), we find that the deceleration is 2.5 m/s^2. Then, using the formula: force = mass * acceleration, we get a braking force of 200 N.
When speed is doubled the braking distance is doubled also?
This statement is not accurate. In reality, when speed is doubled, the braking distance is quadrupled, not doubled, assuming all other factors remain constant. This is because the braking distance is directly proportional to the square of the initial speed.
What is the braking time from 1.5 to 2 seconds what is the final velocity?
To calculate the final velocity and braking time, we need more information such as initial velocity, acceleration, or distance traveled during braking. It is not possible to determine the final velocity and braking time with only the given time interval of 1.5 to 2 seconds.
What was the initial plan of Lincoln for releasing enslaved Africans?
He didn't have an initial plan to release slaves. He planned to take down the South and freeing the slaves was an extra bonus for him
Is it bad for your car if new brake pads squeak?
Generally new pads will contain a layer of dust which causes the initial squealing. The squeal should go away after a bit if driving.
If 4s to brake at 2400 rpm what is the magnitude of acceleration?
To calculate acceleration when braking, we need more information such as the initial speed. Given that the braking time is 4 seconds and the final speed (0 rpm) is 2400 rpm, we can find the acceleration. The magnitude of acceleration can be determined using the formula: acceleration = (final velocity - initial velocity) / time.
A braking time of 1.5 to 2 seconds what is the final velocity?
You need more details.The final velocity could be 0However, you need to know the initial velocity, and the braking acceleration, and perhaps other acceleration/deceleration factors to know the true answer.
I have some physics homework concerning braking force and I am having some trouble with it. How do you calculate the average braking force?
The average braking force can be calculated by dividing the change in momentum by the time taken to come to a stop. This can be expressed as (final speed - initial speed) / time. Remember to convert the speed into appropriate units before performing the calculation.
What happen to the braking distance if the speed is doubled and why?
Hi there! Assuming that the deceleration (or negative acceleration, if you will) is constant and the same in both cases, you can use a special kinematic formula to solve the problem. The formula follows: (final velocity)^2 = (initial velocity)^2 + [ 2 * (deceleration) * (braking distance) ] Rearranged to our needs the formula reads: braking distance = [1/2] * -(initial velocity)^2 / (deceleration) * this equation assumes that the final velocity is zero If the initial speed were doubled then the general formula would read: braking distance = 2 * -(initial velocity)^2 / (deceleration) NOTICE that the two equations are the exact same except for the leading coefficients. 1/2 is assocaited with the braking distance of the normal velocity while 2 is assocated with the breaking distance of the doubled velocity. Since 2 is four times larger than 1/2, this leads us to the conclusion that the breaking distance for an object traveling at double a certain velocity would be 4x greater than the breaking distance of the object moving at the "regular" velocity.
How can the velocity of a car during breaking at a constant acceleration against time from the moment of applying the breaks?
The velocity of a car during braking with constant acceleration can be calculated using the kinematic equation: final velocity = initial velocity + acceleration * time. As the car brakes, the initial velocity decreases to 0 m/s (assuming the car comes to a stop), and the acceleration due to braking is negative. Therefore, the equation becomes: final velocity = -acceleration * time.
A 1000 kg car moving at 10 m s brakes to a stop in 5 s the average braking force is n?
The average braking force can be calculated using the formula: [ \text{Average braking force} = \frac{\text{Change in momentum}}{\text{Time taken}} ] First, calculate the initial momentum of the car: ( \text{initial momentum} = 1000, \text{kg} \times 10, \text{m/s} ). Next, calculate the final momentum of the car when it comes to a stop. The change in momentum is the difference between the initial and final momentum. Finally, divide the change in momentum by the time taken to brake (5 s) to find the average braking force in newtons.
