Respuesta :
Assuming constant acceleration, the distance travelled in the first 4.5s is:
0.5*5.0*4.5 = 11.25m
The distance travelled in the next 4.5s is:
5.0*4.5 = 22.5m
The total distance travelled is:
11.25 + 22.5 = 33.75m
0.5*5.0*4.5 = 11.25m
The distance travelled in the next 4.5s is:
5.0*4.5 = 22.5m
The total distance travelled is:
11.25 + 22.5 = 33.75m
The total distance traveled by the bike is 33.75 m.
Explanation:
Given that,
Initial speed u= 0.0 m/s
Final speed v= 5.0 m/s
Time [tex]t_{1}= 4.5 s[/tex]
Time for constant speed [tex]t_{2}= 4.5s[/tex]
We need to calculate the total distance traveled by the bike
Using formula for the distance
[tex]d=d_{1}+d_{2}[/tex]
[tex]d=(\dfrac{v+u}{2})\times t_{1}+v\times t_{2}[/tex]
Where,
v = final speed
u = initial speed
[tex]t_{1}[/tex] = time for first accelerates
[tex]t_{2}[/tex] = time for constant speed
Put the value into the formula
[tex]d=(\dfrac{5+0}{2})\times4.5+5.0\times4.5[/tex]
[tex]d=33.75 m[/tex]
Hence, the total distance traveled by the bike is 33.75 m.
