Answer:
Time taken by Jesse to bring his bicycle =5.4 Sec
Explanation:
acceleration of bicycle = -2.5 m/sec²
Initial velocity of by cycle u =13.5 m/sec,
final velocity of bicycle v = 0 (since bicycle completely stop finally)
Let the time taken to stop the bicycle completely = t sec
We now by equation of motion,
[tex]v= u + a\cdot t[/tex]
putting the value of u,v & a in the equation
0=13.5 -2.5 x t ( a is taken as negative since velocity of bicycle is reducing)
[tex]t=\frac{13.5}{2.5}[/tex] = 5.4 Sec
