The answer is -0.08m/s²

The cyclist has the acceleration is  -0.08m/s².

What is acceleration?

Acceleration is given by the ratio of resultant or total force acting on any object and the its mass.

It can also be defined as the rate change of velocity with time.

acceleration a = (Δv) / (Δt)

Given is a cyclist is riding his bike up a mountain trail. When he starts up the trail, he is moving with 8 m/s. As the trail gets steeper, he slows to 3 m/s in 1 minute.

1 minute = 60 seconds

The acceleration will be

a = 3 - 8 /60

a = - 0.08333 m/s²

Approximately, acceleration a = - 0.08 m/s²

Thus, the cyclists acceleration is -0.08m/s².
