Question

in the velocity-time graph, two objects make an angle of 45° and 60° with the time axis. then,the ratio of their acceleration is​

Answer 1

Answer:

Between time interval 20 s te 40 s, there is non-zero acceleration and retardation. Hence, distance travelled during this interval

= Area between time interval 20 s to 40 s

=
