A body mass 10kg is acted on by a constant force of 20N for 3 seconds. Calculate the end of the time

Answer 1

To find the final velocity of the body at the end of 3 seconds, we first need to calculate the acceleration of the body using Newton's second law:

F = ma

20N = 10kg * a

a = 2 m/s^2

Now, we can calculate the final velocity using the formula:

v = u + at

where:
v = final velocity
u = initial velocity (assumed to be 0 m/s since not given)
a = acceleration (2 m/s^2)
t = time (3 seconds)

v = 0 + 2 * 3
v = 6 m/s

Therefore, the final velocity of the body at the end of 3 seconds is 6 m/s.
