Question

an object has an initial velocity of 10 centimetre per second and is being accelerated at a constant rate of 5 centimetre per second square .what is its velocity after 5 second? don't copy answer by ur own​

Answer 1

Answer:

Final velocity = 35cm/ s.

Explanation:

Initial velocity u = 10 cm/ s

Acceleration a = 5 cm/s^2

Time t = 5 sec

Final velocity be v.

By first equation of motion :

v = u + at

v = 10 + 5 x 5

v = 10 + 25

v = 35 cm/ s

Answer 2

Answer:

v = 2.5 cm per s

Explanation:

u=10 cm per s

a=5cm per s sq

t =5s

by a=v-u/t

v=-a×t/u

v=-5×5/10

v=-2.5cm per s
