Physical science help? Acceleration and Momentum? - cen racing fre manual
Have in my class science, we are a laboratory of the cars in the spa area with a toy race car and I am in some of the questions we have answered stuck. =)
Find the acceleration:
# 1 25 cm = 25 divided by 3.63 = 6.88 CEN / s. V = 3.63.
# 2 50 cm = 50 divided by 3.40 = 14.70 CEN / s. V = 3.40.
I do not know how to find the acceleration, please help!

1. They found the average speed is velocity.Final
twice the average velocity, / v = 2 * 6.88 = 13.76 cm s.
Acceleration = change in velocity / time = 13.76 to 0 / 3.63
3.79 cm / s ^ 2
2. a = 2 * 14.7 / 3.4 = 8.65 cm / s ^ 2
Or use a = 2s / t ^ 2 = 2 * 50 / (* 3.4 ^ 2) = 8.65 cm / s ^ 2

Please note that you wrote that 6.88 CEN / s. This means that the speed and
V = 3.63 is wrong and time.
Provide accurate information.
