A car travels in a straight line for 5.4 h at a
constant speed of 79 km/h .
What is its acceleration?
Answer in units of m/s2.

  • Physics -

    constant speed is zero acceleration.

  • Physics -

    A car, moving along a straight stretch of high- way, begins to accelerate at 0.0121 m/s2. It takes the car 66.5 s to cover 1 km.
    How fast was the car going when it first began to accelerate?
    Answer in units of m/s.
