Laurie pushes Michael forward off a frozen pond onto a frozen patch of grass at 43.6 m/s. He slows down to 88.8 m/s and glides for 58.6 m. What was his acceleration?

I have to round this to hundredths place.
Send help, please.

how is going from 43.6 m/s to 88.8 m/s "slowing down"?

Vo = 88.8 m/s? = Initial velocity.

V = 43.6 m/s? = Final velocity.

V^2 = Vo^2 + 2a*d = 43.6^2.
88.8^2 + 2a*58.6 = 1901,
117.2a = -5984.4,
a = -51 m/s^2.

To find the acceleration, we need to use the formula for acceleration:

Acceleration (a) = (Final Velocity - Initial Velocity) / Time

However, we need some additional information to calculate the acceleration:

1. We need the initial velocity of Michael when he was pushed.
2. We need the time it took for Michael to glide over the given 58.6 m.

Please provide the missing information so that we can calculate the acceleration accurately.
