Question

98. Each of the three graphs represents acceleration versus time
for an object that already has a positive velocity at time t,
Which graphs show an object whose speed is increasing
for the entire time interval between t, and ty?
III
ti t2t t2
(a) graph I, only (b) graphs I and II, only
(c) graphs I and III, only (d) graphs I, II, and III
​

Answer 1

Answer:

b

Explanation:

becouse for 1&2 (a-t) graph slope is positive means velocity is increasing with time

Answer 2

Answer:

d

PLZ MARK IT AS THE BRAINLIEST!!!

.

Explanation: Since acceleration is positive (+ve) in all the 3 graphs , so the speed will increase in all the 3 graphs.
