a = change in velocity / change in time
= ( 0 - 10.5) / 5.2 m/s^2
x = (1/2) a t^2
= (1/2) * a from above * (5.2) * (5.2)
Mrs bautista accelerates her bicycle uniformly along a straight path from 10.5 m/s to rest in 5.2s.
A. What is her acceleration?
B. What is her displacement during this time interval?
2 answers
by the way part B is also the average speed times the time
x = 5.25 * 5.2
x = 5.25 * 5.2
