Spot the dog is running after a ball. in 22m, he accelerates at a constant rate, and his velocity increases from 5.0m/s to 11m/s. what was his acceleration.

Here it is given that speed of the dog will increase from 5 m/s to 11 m/s in order to cover the distance of 22 m

so here we can use kinematics to find the acceleration

now we will have

so here it will accelerate with a = 2.18 m/s^2

explanation:

an enlarged virtual image is the answer

they should be similar or the same
