Answer:
1.26m/s; 4.96m/s
Explanation
Acceleration is defined as the change I'm velocity of an object with respect to time.
Mathematically,
Acceleration (a) = change in velocity (v-u)/time (t)
Where v is the final velocity
u is the initial velocity
From the equation, it can be deduced that;
v = u+at
If the runner had an initial vertical velocity of -0.7 m/s over a period of 0.2seconds, its final velocity;
v = (-0.7)+9.81(0.2) (a=g=9.81m/s²)
v = -0.7+1.962
v = 1.26m/s
If the runner had an initial horizontal velocity of 3 m/s over a period of 0.2seconds, its final velocity;
v = 3+9.81(0.2)
v = 3+1.962
v = 4.96m/s
