The average speed is the distance per time ratio. velocity is the rate at which the position changes
Answer:
600 J
Explanation:
The formula to find the kinetic energy of an object is
- m = mass in kg
- V = velocity in m/s
- KE is measured in Joules just as all other forms of energy.
Now, let's plug in the variables we're given and simplify.
Thus, the answer is 600 Joules.
Answer:
40°
Explanation:
when a ray light is incident on a surface it makes a 40° angle with the normal to the surface (reflecting surface ). this called angle of incidence.
And the angle made by reflected ray with the normal to the surface is called angle of reflection.
by the law of reflection angle of incidence is equal to the angle of reflection
hence the answer to the question is 40° ( because ∠i =∠r )
Answer:
F = 13333.333 N = 13.33 KN
Explanation:
From Newton's second law of motion, the change in momentum = the impulse.
Mathematically,
Impulse = Change in momentum.
Impulse = (Force) × (time during which it acts) = F.t
Magnitude of the Change in momentum = mv (there is no final momentum as the paint sticks to the spacecraft window)
F×t = m×v
t = (6.00 ✕ 10⁻⁸) s
m = 0.160 mg = (1.6 × 10⁻⁷) kg
v = (5.00 × 10³) m/s
F × (6.00 ✕ 10⁻⁸) = 1.6 × 10⁻⁷ × 5.00 × 10³
F = 13333.333 N = 13.33 KN
Hope this Helps!!!
A weight would be least affected since it would fall striaght down if it was say paper it would go down slower because it has more air resistance due to less weight
