Answer:
The acceleration of a ball is 5 m/s².
Explanation:
Given that,
Initial velocity = 20 m/s
Time = 2.0 sec
Final velocity = 30 m/s
We need to calculate the acceleration
Using equation of motion
Where, v = final velocity
u = initial velocity
t = time
Put the value into the formula
Hence, The acceleration of a ball is 5 m/s².
I hope this a little bit.
679.08 lbs
Here it is given that
= Mass of first person = 175 pounds
= Height of first person = 70 inches
= Mass of second person
= Height of second person = 110 inches
The weight of the second person would be 679.08 lbs
