Answer:
32 meters
Step-by-step explanation:
Use the formula for displacement
d = ut + (1/2)at²
where u = initial velocity , a is the acceleration and t is the time traveled
First let's find the acceleration given by (v - u)/t where v is the final velocity and t the time taken to reach this final velocity from initial velocity u
v = 0 , t = 4 secs, u = 16 m/s
a = (0 - 16)/4 = -16/4 = -4 m/s²
Plugging in values for u= 16 and a = -4 we get
So d = 16t + (1/2)(-4)t
= 16t -2t
Plugging in value for t = 4 gives us
= 16 x 4 - 2 x 4 x 4
= 64 - 32
= 32 meters
