Answer:
a. 4.15 m/s.
Explanation:
Given the following data;
Acceleration, a = -0.100 because it's in the opposite direction.
Final velocity = 4
Distance = 6
To find the initial velocity of the ball, we would use the third equation of motion;
Where;
- V represents the final velocity measured in meter per seconds.
- U represents the initial velocity measured in meter per seconds.
- a represents acceleration measured in meters per seconds square.
- S represents the displacement measured in meters.
Making U the subject, we have;
Substituting into the equation, we have;
Taking the square root of both sides;
U = 4.147m/s ≈ 4.15m/s
Therefore, the initial speed of the ball is 4.15m/s.
