Angular velocity means how many radians/degrees is this hand passing by every second.
First, you realize it goes through a whole revolution (2
in radians) in 60 seconds.
This means for every second, it passes by:
For the next part, you need to know this equation:
Tangential velocity=Angular velocity x radius (meters)
Answer:
62 N
Explanation:
Sum of the forces on the toolbox:
∑F = ma
T − mg = ma
T = mg + ma
T = m (g + a)
T = (5.0 kg) (9.8 m/s² + 2.5 m/s²)
T = 61.5 N
Rounded to two significant figures, the force exerted by the rope is 62 N.
Answer:
A balloon is floating up into the air at 1 m/s.
Explanation:
Velocity is the displacement divided by the time;
Velocity = 
It is a vector quantity that has magnitude and direction.
The choice that shows a change in direction is a correct specification of velocity.
A balloon floating up into the air at 1m/s shows no directional change.
Answer
given,
F₁ is horizontal = 40 N
F₂ is normal = 20 N
F₃ is parallel = 30 N
work done by
W₂ = 0 as force is acting perpendicular to the direction of motion.
as the motion moved to 0.8 cm
W₃ = F₃ x d
W₃ = 30 x 0.8
W₃ = 24 J
W₁ = F₁ x d
W₁ = F₁ cos ∅ x d
W₁ = 40 cos 30⁰ x 0.8
W₁ = 27.21 J
