Answer is E

time can be negative.
A is not true because a=d2xdt2=12 m/s2
C: question already said that particle move along x-axis, which is not parabola path.
D: velocity is dxdt=12t, therefore velocity changes by 12 m/s and not 9.8 m/s
So we are left with E.

What happens to a satellite that slows down?

Bess [88]

Two things can happen to old satellites: For the closer satellites, engineers will use its last bit of fuel to slow it down so it will fall out of orbit and burn up in the atmosphere. Further satellites are instead sent even farther away from Earth.

A car moved 60 meters west in 2 hours. What is its average velocity?

Fofino [41]

Explanation: Velocity is the displacement of an object during a specific unit of time. Two measurements are needed to determine velocity. Displacement and time. Displacement includes a direction, so velocity also includes a direction. Speed with direction. Velocity can be an average velocity or an instantaneous velocity. Units for velocity are the same as for speed: m/s, km/h, and mph. Delta x(Δx) is the symbol used for displacement. Delta (Δ) means to "change in." Δx means to "change in position." Δx is calculated by final position minus initial position. Velocity formula: → v=Δx/t as a fraction.

v=Δx/t

$v=\frac{xf-xi}{t}= \frac{60m}{2}=30m$

Final answer is 30.

Hope this helps!

Thanks!

Have a great day!
