Answer:
14 m/s^2
Explanation:
We have to use the equation F=ma because the question is a Newton's second law question.
First, list known values
F (force) = 70 N
m (mass) = 5 kg
a (acceleration) = ? (we have to solve for this)
Second, plug in known values into equation.
F=ma
70=5a
Third, solve. To solve this all you have to do is divide both sides by 5
70/5=5/5a
Fourth, your answer will be 14 meters per second squared (m/s^2)
I hope this answer helps and have a great day!
Answer: magnitude = 5 and angle = 160°
Explanation:
A vector has magnitude 5 and angle -20°
A vector can be written in terms of its components as :
using trigonometry identity:
sin θ = -sin ( 180 + θ )
cos θ = - cos (180 + θ)
Thus, we can write the same vector as:
Magnitude
Thus, the magnitude would be A = 5 and angle = 180+θ= 180-20 = 160°

Explanation:
take coordinate system correctly. use formulas of projectile motion
I’d say a stronger force because the moon doesn’t float away. But I’m

Answer:
Explanation:
speed of alien spaceship = .1 c
We shall apply formula of relativistic mechanics to solve the problem
relative velocity =
Here v = v₁ = .1 c
relative velocity = .1c + .1 c / 1 - .1²
= .2 c / .99
= .202 c
The earth would receive the signal at the speed of .202 c .
