Answer:
30m/s
Explanation:
From law of motion equation
Vf= Vi + at
Where Vf= final velocity
Vi= initial velocity=0(the car started at rest)
a= acceleration= 3m/s2
t= time= 10s
Then substitute into the equation to get the final velocity.
Vf= 0+(10×3)
Vf= 30m/s
Hence, the car's final velocity is 30m/s

Answer:
Pam's velocity when she crosses the finish line is 10 m/s.
Explanation:
Given;
initial velocity of Pam, u = 3.3 m/s
acceleration of Pam, a = 3 m/s²
last distance covered, d = 15 m
let her final velocity = v
Apply the following kinematic equation to determine Pam's final velocity;
v² = u² + 2ad
v² = 3.3² + 2(3)(15)
v² = 10.89 + 90
v² = 100.89
v = √100.89
v = 10 m/s
Therefore, Pam's velocity when she crosses the finish line is 10 m/s.
