The first part is pretty straight forward, vₓ=v₀+a(t). Convert final velocity to m/s to get 97.2m/s. v₀=0, a=4. Solving for t yields 24.3 seconds.
For the second part use "vₓ^2(final velocity) = v₀^2(initial velocity) + 2a(Δx). Final velocity is 97.2m/s, initial velocity is 0, acceleration is 4m/s^2. Solving for Δx yields 1181.53 meters.
Answer
given,
mass of book = 0.305 Kg
so, from the diagram attached below
computing horizontal component
θ = 62.35°
Answer:
The moons of the outer planets are made of a mixture of ice and rock but our moon is made of only rock
Explanation:
When it comes to moon the elements silicon, iron & oxygen are classified as rocky materials and the elements carbon, nitrogen & Oxygen-Hydrogen compounds are classified as icy materials.
Our moon is primarily made of Silicon, aluminum, iron, calcium and iron.
Moons of outer planets are made of both icy materials and rocky materials.

Higher-level consumers get the most energy from food they eat.
An example is a lion eating a zebra. The zebra has more energy than a handful of grass, which has almost none to offer.
