Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity [m/s]
Vo = initial velocity [m/s]
a = acceleration [m/s²]
t = time [s]
First case
Vf = 6 [m/s]
Vo = 2 [m/s]
t = 2 [s]
Second case
Vf = 25 [m/s]
Vo = 5 [m/s]
a = 2 [m/s²]
Third case
Vo =4 [m/s]
a = 10 [m/s²]
t = 2 [s]
Fourth Case
Vf = final velocity [m/s]
Vo = initial velocity [m/s]
a = acceleration [m/s²]
t = time [s]
Fifth case
Vf = final velocity [m/s]
Vo = initial velocity [m/s]
a = acceleration [m/s²]
t = time [s]
