Answer:
4kg
Explanation:
Given parameters:
Kinetic energy = 1.6J
Velocity = 0.2m/s
Unknown:
Mass of the body = ?
Solution:
The kinetic energy of a body is the energy due to the motion of the body.
It is mathematically expressed as;
Kinetic energy = 
m v²
m is the mass
v is the velocity
1.6 = x 0.2 x v²
1.6 = 0.1v²
v² = 16
v = 4kg
With same braking power you will be stopping faster on the original weight therefore the answer to fill the blank is increase. The stopping distance will increase as there'll be higher energy to dissipate than lighter cars applied with the braking force similar with that of the lighter car. Also the skid and drag will add to the distance as well as the inertia of the moving heavier vehicle would be greater as well.

Answer:
-5 meters
Explanation:
x = 3t² + 2t − 5
The initial displacement is when t = 0.
x = 3(0)² + 2(0) − 5
x = -5
