The graph below shows the relationship between speed and time for two objects, A and B. Compare with the acceleration of object
B, the acceleration of object A is
A. Greater
B. The same
C. Lesser
D. One-third as less
2 answers:
Answer:
A) greater
Explanation:
acceleration is calculated by dividing velocity over time..so by calculating, you find acceleration of A is greater than that of B

The formula we can use in this case is:
v = v0 + a t
where v is final velocity, v0 is initial velocity, a is
acceleration and t is time
So finding for v0:
v0 = v – a t
v0 = 43.7 – (2.5) 2.7
v0 = 36.95 m/s
