Question

A 3.00-kg block starts from rest at the top of a 35.5° incline and slides 2.00 m down the incline in 1.45 s. (a) Find the acceleration of the block.

Answer 1

0.344 m/s^2

Step-by-step explanation:

The first step is to calculate V

V= distance /time

= 2/1.45

= 1.379 m/s

Therefore the acceleration of the block can be calculated as follows

a= V - U/2d

= 1.379 - 0/2×2

= 1.379/4

= 0.344 m/s^2
