Question

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

Answer 1

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,

$$\begin{gathered} v=u \\ v=10m/s \end{gathered}$$

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