(d) Acceleration is a vector quantity
Answer:
The big rip theory
Explanation:
I believe what you are referring to is the big rip theory, in which the universe expands faster than the speed of light Kurzgesagt refers to it as a "horizon" but in reality it's a little more complicated than that. Eventually the expansion of the universe will accelerate far beyond the speed of light creating space between molecules until eventually all matter is fleeting and the entire universe is an endlessly vast cosmic void with not but the occasion molecule left from a time when things weren't so lonely.
Answer:
v=8m/s
Explanation
The initial velocity, u, of the car=32m/s
Since the car has decelerated, we negate the acceleration
This implies that,
Time,t=4s
Let v be the final velocity,
using the relation,
We obtain the below by substitution
By cross multiplying we obtain,
v=8m/s
