Tommy was walking at a rate of 4 miles per hour at noon and at 12: 30 pm he was walking at a brisk rate of 6 miles per hour. two hours later tommy was walking at a leisurely rate of 2 miles per hour. what was tommy’s acceleration between noon and 12: 30 pm?

Tommy’s acceleration between noon and 12:30 pm is 4 miles/hr².

Explanation:

Given that,

Initial velocity = 4 miles/hr

Final velocity = 6 miles/hr

Time t = 30 minutes

Acceleration :

Acceleration is the rate of change of the velocity of the particle.

We need to calculate the Tommy’s acceleration between noon and 12:30 pm

Using equation of motion

Where, v = final velocity

u = initial velocity

a = acceleration

t = time

Put the value into the formula

Hence, Tommy’s acceleration between noon and 12:30 pm is 4 miles/hr².
