PYQ NEET- Newton'S First Law Of Motion

1.

The answer is 20 m/s.

The formula for the final velocity of an object after being acted upon by a force for a certain time is:

v = u + at

Where:

• v is the final velocity
• u is the initial velocity
• a is the acceleration
• t is the time

In this problem, we are given that the initial velocity is 10 m/s, the force is 5 N, and the time is 10 s. We can find the acceleration by dividing the force by the mass:

a = F / m

a = 5 N / 10 kg

a = 0.5 m/s^2

Now we can plug these values into the formula for the final velocity:

v = u + at

v = 10 m/s + 0.5 m/s^2 * 10 s

v = 20 m/s
