Question

When the shuttle bus comes to a sudden stop to avoid hitting a dog, it decelerates uniformly at 5.4 m/s2 as it slows from 9.2 m/s to 0 m/s. Find the time interval of acceleration for the bus

Answer 1

Uniform Acceleration: a(t) = -5.4 -- Negative to indicate deceleration.
Related Velocity: v(t) = -5.4t + v0 -- Where v0 is the initial velocity.
Related Velocity: v(t) = -5.4t + 9.2

Solve for t: v(t) = 0
