Question

Choose an equation from the following list: x=x0 +Vox t + (12) ax t2 ox2 ar (x-xo) A small block has constant acceleration as it slides down a frictionless incline. The block is released from rest at the top of the incline, and its speed after it has traveled 6.60 m to the bottom of the incline is 3.80 m/s.

Answer 1

Since the question is not complete assuming the question such that to find the speed of the block when it is at 5 m average velocity V_avg = 3.80/2 = 1.90m/s Time taken t = 6.60/1.90 = 3.473s Constant acceleration a = 3.80/3.473 = 1.094 m/s^2 Time taken to travel 5m d = 1/2 at^2 5.00 = 0.5 times 1.094 times t^2 t = squareroot 5/0.5 times 1.094 = 3.023s Speed of block when it is at 5 m v = at = 3.023 times 1.094 = 3.30 m/s
