Question

in 2.0 sec, a car increases its speed from 60km/h to 65km/h while a bicycle goes from rest to 5km/h. which has greater acceleration?​

Answer 1

Answer:

Explanation:

The delta part of this equation is very important, as it means that the equation uses CHANGE in speed, not just the speed. The change in speed for the car is 5 km/h, not 65km/h.  

The bicycle's change in velocity is also 5 km/h, as it went from 0-5km/h, and therefore, assuming the bicycle also takes 2.5 seconds to accelerate to this speed, both the bicycle and the car will have accelerated at the same rate.  

Hope this helps. =)
