Answer:
1.96 m/s^2
Explanation:
angle of inclination, θ = 30.6°
coefficient of friction, μ = 0.36
Acceleration of the crate
a = g Sin θ - μ g Cos θ
a = 9.8 ( Sin 30.6 - 0.36 x Cos 30.6)
a = 9.8 ( 0.509 - 0.309)
a = 1.96 m/s^2
Thus, the acceleration f the crate is 1.96 m/s^2.
Answer:
–50.96
Explanation:
The following data were obtained from the question:
Initial velocity (Vᵢ) = 0 m/s
Acceleration (a) = – 9.8 m/s²
Time (t) = 5.2 s
Final velocity (Vբ) =.?
Acceleration is simply defined as the change of velocity with time. Mathematically, it is expressed as:
Acceleration (a) = Final velocity (Vբ) – Initial velocity (Vᵢ) /Time (t) =
a = (Vբ – Vᵢ) / t
With the above formula, we can determine how fast the object is traveling after 5 s as follow:
Initial velocity (Vᵢ) = 0 m/s
Acceleration (a) = – 9.8 m/s²
Time (t) = 5.2 s
Final velocity (Vբ) =.?
a = (Vբ – Vᵢ) / t
– 9.8 = (Vբ – 0) / 5.2
– 9.8 = Vբ / 5.2
Cross multiply
Vբ = –9.8 × 5.2
Vբ = –50.96 m/s
Therefore, the object is traveling at
–50.96 m/s
Answer:
a solar eclipse occurs when the moon passes in front of the sun,blocking it out partially or completely. the eclipse results in parts of the earth being covered in the shadow of the moon. a lunar eclipse occurs when the moon passes directly behind earth and into its shadow.
Explanation:
Answer:
Net force = 25N and in the right direction
Explanation:
mass of box, m = 50kg
Force of block = 150N
Friction force = 125N

150 - 125 = 25N
the force applied to the block is greater than the friction force. there the force applied will overcome the friction force and move in the right direction of the force applied
