Answer 1

Answer:

20m/s

Explanation:

it takes total of 6 secs from throwing to reach the ground , so there are two intervals - 1. ball from ground to upward and 2. from upward to ground , and each interval takes time of 3 secs as total time is 6 secs and two intervals , so one interval takes 6 divide by 2 which is 3 seconds.And for speed , speed =distance divide by time. and 60 meteres divide by 3 secs = 60 divide by 3= 20 and hence, speed is 20 m/s
