Answer:

1) Uniform acceleration means that the acceleration of the car remains the same over a period of time. ... Non uniform acceleration means that the acceleration of an object is not constant, but either increasing or decreasing over a passage of time.

2) In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). ... that object's mass, depending on the materials out of which it is made — magnitude is inversely proportional to the object's mass.

3) Using Newton's third equation of motion i.e. Yes, you can find distance using: Vi x t + 1/2 a x t^2 and get the correct answer (37.5 m). But, another insightful way to look at it is this: Average speed of 5 and 10 m/s is 7.5 m/s.

Answer:

  1. uniform acceleration:: when a body changes its velocity at a uniform rate with respect to time.

non uniform acceleration: when a body changes its velocity at a non uniform rate ,the motion is said to be in non uniform acceleration.

2. acceleration is the change in velocity e with respect to time .the acceleration is taken to be positive if it is in the direction of velocity and negative when it is opposite to the direction of velocity the SI unit of acceleration is metre per second square.
