**Answer:**

20 m/s

**Explanation:**

First, we calculate for the acceleration down the incline using .

a = (9.80)sin(20°)

a = 3.35

Then, we use one of the kinematics equations, .

= 0 m/s

a = 3.35

= 62 m

Because you are constantly changing direction it means there is a constant force acting on you and that means you are accelerating.

**Answer:**

electrical energy into light energy.

hope it helps.

**Answer:**

1.6 ns

**Explanation:**

Given data :

delay in 10-bit adder = 1ns

setup time = 0.3 ns

hold time = 0.1 ns

propagation delay = 0.2 ns

<u>calculate the minimum cycle time </u>

∑ delay + setup time + hold time + propagation delay

= 1 + 0.3 + 0.1 + 0.2

= 1.6 ns

**Answer:**

Propulsion system, antigravitational tech

**Explanation:**

Fuel is extremely inefficient and expensive not to mention it weighs a lot. You really only need to reach escape velocity to leave earth. The rest is just a little amount of boosting to alter course and slow down for landing. I couldn't really think of much. Once we have an antigravitational system then you could say the whole rocket is holding you back because the design would be different. Nobody really knows how to defy gravity but that would be a technolgical limitation for sure.
