Answer: 37.5 kg in 3 s.f.
Explanation:
They’re right that is the answer
Explanation: As the angle is increased the acceleration of the object is increased as the angle increases the component of the force parallel to the incline increases and the component of forced perpendicular to the inclined decreases it is the parallel component of the weight vector that causes the acceleration.
Answer:
Say you are holding a thread to the end of which is tied a stone. Now when you start whirling it around you will notice that two forces have to be applied simultaneously. One which pulls the thread inwards and the other which throws it sideways or tangentially.
Both these forces will generate their respective accelerations.
The one pointed inwards will generate centripetal or radial acceleration.
The one pointing sideways will generate tangential acceleratio
Explanation:
A major difference between tangential acceleration and centripetal acceleration is their direction
Centripetal means “center seeking”. Centripetal acceleration is always directed inward.
Tangential acceleration is always directed tangent to the circle.
Tangential acceleration results from the change in magnitude of the tangential velocity of an
object. An object can move in a circle and not have any tangential acceleration. No tangential
acceleration simply means the angular acceleration of the object is zero and the object is moving
with a constant angular velocity
Answer:
V = 4.48m/s a = 1.57m/s²
Explanation:
ω₀ = 16rad/s
α₀ = 5.6rad/s²
r = 280mm = 0.28m
a = ?
v = ?
Angular velocity (ω₀) = velocity of acceleration / length of path
ω₀ = v / r
V = ω₀ * r
V = 16 * 0.28
V = 4.48m/s
Acceleration = ?
Angular acceleration α₀ = angular velocity (ω) / time take (t)
α₀ = ω / t .... equation i
But acceleration (a) = velocity (v) / time (t)
a = v / t
t = v / a
Put t = v / a into equation i
α₀ = ω / (v / a)
α₀ = ω * a / v
α * v = ω * a
a = (α * v) / ω
a = (5.6 * 4.48) / 16
a = 1.568m/s²
a = 1.57m/s²
