A skateboard is moving to the right with a velocity of 8 m/s after a steady Gust of wind that last 5 seconds the skateboarder is
1 answer:
The acceleration of the skateboard is (to the left)
Explanation:
The motion of the skateboard is a uniformly accelerated motion, so we can use the following suvat equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time
For the skateboard in this problem, choosing right as positive direction, we have:
u = +8 m/s is the initial velocity
v = +5 m/s is the final velocity
t = 5 s is the time
Solving for a, we find the acceleration:
And since the sign is negative, the direction is to the left.
