<span>An object is acted upon by a force of 22 newtons to the right and a force of 13 newtons to the left.
(1) 22 N to the right
(2) 13 N to the left.
magnitude = 22 - 13
magnitude = 9
Direction would be to the right.
So magnitude is 9N direction to the right.</span>
Explanation:
Given:
v₀ = 22 m/s
v = 0 m/s
t = 17.32 s
Find: a
v = at + v₀
(0 m/s) = a (17.32 s) + (22 m/s)
a = -1.270 m/s²
Round as needed.
To solve this problem we will use the kinematic formula for the final velocity.

The final speed is 0 at the moment the player stops.
The time until it stops is 1.3 s
The initial speed is 200 feet / s Note (check the speed units in the problem statement, 200ft / s is very much and 200ft / h is very small)
Then, we clear the formula.

Because the player is slowing down, the acceleration goes in the opposite direction to the player's movement, and that is why it is negative.
To answer part b) we use the following formula.

0.0605J is your answer. Use the formula KE=1/2mv^2
