Answer:
4/3 seconds
Step-by-step explanation:
Use the kinematic or SUVAT equation that involves initial velocity, final velocity, acceleration and time since these are what we know and what we want to find;
This formula is: v = u + at
v = final velocity
u = initial velocity
a = acceleration
t = time
Then, simply substitute variables with known values and rearrange or solve for t:
4 = 8 + (-3)t
4 = 8 - 3t
3t = 8 - 4
t = 4/3
