Question

Starting from the rest Dilip pedals his bicycle to attain a velocity of 6m/s in 25 seconds then he applies brakes so that the velocity of the bicycle come down to 4m/s in the next 4 seconds calculate the acceleration of the bicycle in both the cases

Answer 1

@
u1 = 0
v1 = 6 m/s
t1 = 25 sec
a1=?
A1 = (v1 - u1)/ t1
→ = 6-0 / 25
→ = 6 / 25
→ = 0.24 m/s²
Acceleration 1 = 0.24 m/s²
____________________
u2 = 6 m/s
v2 = 4 m/s
t2 = 4 sec
a2 = ?
A2 = ( v2 - u2)/ t2
→ = 4-6 / 4
→ = -2/4
→ = -1/2
→ = -0.5 m/s²
Acceleration 2 = -0.5 m/s²
