Initial velocity (Vi) = 25 m/s
acceleration (a) =
time interval (t) = 5 sec
let us assume that final velocity after 5 sec be Vf
As acceleration is constant, we can apply the the equation of motion with constant acceleration i.e.
Hence,
so, the velocity of bicyclist will be 5 m/s after 5 sec
Answer:
Explanation:
Given
Initial speed
distance traveled before coming to rest
using equation of motion
where v=final velocity
u=initial velocity
a=acceleration
s=displacement
for
using same relation we get
divide 1 and 2 we get
So a distance if 213.32 ft is required to stop the vehicle with 80 mph speed
