Answer:
2 m/s^2, west
Explanation:
Vf=final velcoity
Vi=initial velocity
t=timw
[tex]a = \frac{vf - vi}{t} [/tex]
=
[tex] \frac{15 - 25}{5} [/tex]
= - 2 m/s^2
The - changes direction and makes it opposite
2 m/s, west
The magnitude of the object acceleration is -2m/s². Since the acceleration of the object is negative, hence the direction will be towards the west
Acceleration is the change in velocity of a body with respect to time. Mathematically;
[tex]a=\frac{v-u}{t}[/tex]
v is the final velocity
u is the initial velocity
t is the time taken;
Given the following parameters
v = 15m/s
u = 25m/s
t = 5.0secs
Substitute the given parameters into the formula to have:
[tex]a=\frac{15-25}{5}\\a=\frac{-10}{5}\\a=-2m/s^2[/tex]
Hence the magnitude of the object acceleration is -2m/s². Since the acceleration of the object is negative, hence the direction will be towards the west.
