Answer:
0.25223 seconds.
Explanation:
= Mass of bullet = 0.0146 kg
= Mass of block = 2.55 kg
v = Combined velocity
= Velocity of bullet = 816 m/s
g = Acceleration due to gravity = 9.81 m/s²
As linear momentum is conserved

Now
as the block (with the bullet in it) reverses direction and rises,

Equation of motion

The time t is 0.25223 seconds.
Answer:
C. It triples in magnitude (PLATO)
D) How fast you are moving
I’m pretty sure the answer is A
the answer is true because evaporates can provide an ideal speed racing surface
