.

First, calculate the acceleration a = = = = 10 m/s^2. Next, calculate the distance d = + = + = + = 40 + 10*8 = 40 + 80 = 120 meters. ANSWER

Solved.

Hello, if you start study Physics, do you have an appropriate textbook ?

I can recommend you something, if you wish.

comment from student: Ms. Ikelin, What do you recommend for physics??

My response :

1)   If you are between 12 - 15 years old, then

      Taffel - Physics, its Methods and Meaning, 1986 (5 edition) or 1992 (6 ed.)

2)   If you are between 16 - 18 years old, then

      Giancoli - Physics, 6-th edition.

These textbooks are perfect.

The authors love their subject, know it, love to teach and are professional in their job.

You can buy both books in Amazon (used, hardcover) for very cheep price.

Which class/grade are you ?
Did your teacher recommend you something ?
