Question

1)You know that the equation Vf = Vi + at. After applying a data modeling to the data you aquired in the lab, you obtain a numerical equation Vf = 16.32+5.34t. What is the acceleration according to the modeled equation?

2)An object accelerates from 19 m/s to 50 m/s in 15 seconds. What is the objects acceleration in m/s2?

3)An object has an initial velocity of 7.4 m/s. The object accelerates at a constant rate of 3.89 m/s2 for 2.8 seconds. What is the displacement of the object during this period of time?

Explanation / Answer

1)acceleration according to the modeled equation=5.34m/s^2

2))An object accelerates from (v1)19 m/s to (v2)50 m/s in (t)15 seconds=(v-u)/t=2.066m/s^2

3)s=u*t+0.5*a*t^2

=7.4*2.8+0.5*3.89*2.8^2

=35.96m
