Answer 2

Calculation of Instantaneous Velocity

To calculate the instantaneous velocity of an object at the end of the first second, we need to use the equation for uniformly accelerated motion:

v = u + at

Where: - v is the final velocity - u is the initial velocity (which is zero in this case since the body starts from rest) - a is the acceleration - t is the time

Given that the body starts from rest and moves with uniform acceleration, we can assume that the acceleration remains constant throughout the motion.

From the given information, we know that the body traveled a distance of 10 meters in the first second. However, we don't have the value of the acceleration.

Let's assume the acceleration is a. We can now calculate the instantaneous velocity at the end of the first second using the equation mentioned above.

v = 0 + a * 1

Since the initial velocity is zero, the equation simplifies to:

v = a

Therefore, the instantaneous velocity at the end of the first second is equal to the acceleration of the body.

Unfortunately, we don't have the value of the acceleration in this case. If you provide the value of the acceleration, I can calculate the instantaneous velocity for you.
