Question

1)Velocity is uniform in the given time interval
0s to 2s
2s to 3s
3s to 5s
2)Acceleration is uniform in the given time interval
0s to 2s
2s to 3s
3s to 5s
all of these
3)Distance travelled in the first 2s is
20m
40m
60m
80m
4)Acceleration is negative in the time interval
0s to 2s
3s to 5s
in both the above intervals
acceleration is negative neither from 0s to 2s nor 3s to 5s

Answer 2

Answer:

1)Velocity is uniform in the given time interval-

2s to 3s

2)Acceleration is uniform in the given time interval - 2s to 3s

3)Distance travelled in the first 2s is- 80m

(d = St = 2(40) = 80m)

4)Acceleration is negative in the time interval

in both the above intervals (acceleration is decreased)
