Question

A body is moving with a velocity of 10m/s. If the motion is uniform, what will be the velocity after 10 seconds?

Solution

Step 1: Given data

A body is moving with a velocity of 10m/s.

Step2: Uniform motion

  1. Uniform motion is a type of motion in which an object moves in a straight path at a constant speed.
  2. This means that the body's velocity remains constant because it travels the same distance in the same amount of time.
  3. The body's acceleration will be 0 in the event of uniform rectilinear motion.
  4. The object's average speed will be equal to its actual speed in this case.
  5. A car travelling at a constant pace, a boy sprinting in a straight line at a constant speed, and so on are examples of uniform motion.

Step 3: Calculating the final velocity 10sec

In uniform motion, the final velocity remains the same as to initial velocity.

v=u.

Initial velocity is 10m/s (given)

Substituting the value of initial velocity we get,

v=uv=10m/s

Hence, velocity after 10sec is 10m/s (remains same).
