Abear is walking through a forest with a velocity of 1.5 m/s when it spots some honey 200 meters ahead. three seconds later, it is running toward the honey with a velocity of 7.5 m/s. what is the bear's acceleration?

The bear's acceleration is

Explanation:

The magnitude of the acceleration can be calculated using the following equation :

(I)

Where ''a'' is the acceleration

Where ''dv'' is the speed variation

Where ''dt'' is the time variation

In this exercise, the time variation is equal to 3 seconds because it is the amount of time in which the bear accelerated from to

The speed variation is equal to :

Where ''vf'' is the final speed and ''vi'' is the initial speed.

Finally, we can calculate the bear's acceleration using the equation (I) :

We find that the bear's acceleration is

v 154.9= 0.9 length length s little over 154.9cm

the answer is 3.1 his answer is wrong mines is right
