What has the greater deceleration a bicycle slowing from 3 m s to a stop in 6 second or a car slowing from 20 m s to 15m s in 6 seconds?

The car has a greater change of speed in the same period of time.
So the magnitude of its acceleration is greater than the bike's is.`1111111111111111111111111111`1
decel = CHANGE in velocity divided by time
in first case decel = 3/6 = .50
in second decel = 5/6 = 0.83 so second case is faster decel

What is the deceleration of a car traveling with a velocity of 30 meters per second slowing down to a velocity of 10 meters per second within 10 seconds?
you doing homework???
A motorcycle slows down from 40 ms to 20 ms If this takes 4 seconds what is the motorcycle's acceleration?
Acceleration(a) = [final velocity(v) - initial velocity(u)] / time(s) Algebrtaically a = [ v - u ] / s A negative result indicates deceleration a = [20 - 40 ]= / 4 a = [-20] / 4 a = -5 m/s^(2) This is negative which matches the question of slowing down/deceleration.
How do you measure or calculate deceleration during a collision?
In a controlled test condition (like crash tests on cars) an accelerometer is used to measure the rate of deceleration. It should be possible to estimate the deceleration following a collision if the speed of the vehicles at the moment of the collision is known. We could do this by measuring the amount the car was crushed/dented during the collision. We know the vehicle decelerated from its starting speed over this distance so we can estimate the average deceleration. I believe there are more sophisticated techniques used by accident investigators. As an aside, in strict physics terminology, slowing down (as well as any other change in velocity) is acceleration, not deceleration however deceleration is often used to imply a reduction in speed in every day English. If you want to get into this further have a look at "Are speed and velocity the same?" and remember that acceleration is also a vector.
If A bus decreases its speed from 80kilometer per hour to 60kilometer per hour in 5 seconds find the acceleration of the bus?
there is none its slowing so its decelerating
How long would it take to travel 72 miles at 75 mph?
About 57 minutes 36 seconds. This is the driving time at that speed and does not include slowing, accelerating or stopping during the trip.
The term deceleration means?
slowing down.
What is rate of deceleration?
The rate of deceleration is how quickly something is slowing down.
Deceleration is the rate of?
slowing down
An object slowing down has a what acceleration?
Deceleration
An object that is slowing down is undergoing acceleration?
no, deceleration.
What the term deceleration means?
That means slowing down.
What is negative acceleration also called?
Negative acceleration is also called as deceleration.
Which has the greater deceleration a bicycle slowing from 3 meter per second to a stop in 6 seconds or a car slowing 20 meter per second to 15 meter per seconds in 6 seconds?
Acceleration = (change in speed)/(time for the change)Bike: (0 - 3)/6 = -1/2 meter per second2Car: (15 - 20)/6 = -2/3 meter per second2Both accelerations are negative. The car's is greater.We could have seen that right away, without all the calculations, just by noticingthat the car loses more speed in the same amount of time ! That's why I couldn'tscore bubkes on the GE College Bowl.
What is the term for negative acceleration?
deceleration aka slowing down?
What is the deceleration of a car traveling with a velocity of 30 meters per second slowing down to a velocity of 10 meters per second within 10 seconds?
you doing homework???
What is another word for slowing down?
decreasing 2nd Answer: "Deceleration", actually.
What is a decrease in the magnitude of velocity called?
It is called deceleration or slowing down.
