Help me and get points... Please

If you walk to the edge of a cliff and
throw a ball upward at 60 m/s, how
many seconds will it take for the ball
to be traveling at 30 m/s downward?

According to your question,

acceleration due to gravity on earth, a = 9.8m/s

initial velocity, u = 0

final velocity, v = 30m/s

As we know that, v = u + at

So,

keep smiling ❣️

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow
