Answer:
The horizontal component is 96.42 N
The vertical component is 114.91 N
Explanation:
A force 150 newtons is inclined at 50 degrees to the horizontal direction
We need to find its component in the horizontal and vertical directions
is the horizontal component
is the vertical component
Look to the attached figure:
The horizontal component is the product of F and cosine
the angle between F and the horizontal
The vertical component is the product of F and sine
the angle between F and the horizontal
→ = F cos(50)
→ = 150 cos(50)
→ = 96.42 N
→ = F sin(50)
→ = 150 sin(50)
→ = 114.91 N
<em>The horizontal component is 96.42 N</em>
<em>The vertical component is 114.91 N</em>
Answer:
a) tires rubbing, b) the weight has a component parallel to the floor
c) he child's back support, d) The tension of the rope and weight
Explanation:
In this exercise, we are asked to indicate the origin of the forces for the centripetal movement parallel to the rope, e) gravitational force
a) When a car turns, the centripetal force has two origins
* The tires rubbing against the road
* If the road has a lean angle, the component of the weight directed towards the center of the circle also contributes to the centripetal force.
b) the child in general has some degree of inclination with respect to the post, for which the weight has a component parallel to the floor that is responsible for the centripetal movement of the system
c) The bench rotates together with the carousel, so the child's back support is the response to the centripetal force
d) The tension of the rope has two components: the component perpendicular to the movement and the component of the weight (parallel to the rope) the difference of these two forces is the centripetal force
e) The gravitational force of the sun on the earth is what creates the centripetal motion
Answer:
6logs
Explanation:f
First finding the volume of the logs
V= π/4d²l
= 0.098m³
So number of logs will be
Weight of 2 boys + weight of log = buoyancy force.
So
2( 400)+ N ( Mlog x g) = density of water x volume displaced x g
2(400) = N x 0.098x 1000x 9.8 x 0.9- 0.75* 1000
N= 5.5 which is approx 6logs
Lydia is an example of an optimist. Optimists always look at the positive side of a particular situation. They believe in a positive result. Optimist always see "the bright side" as opposed to the pessimist. The word optimism comes from latin word "optimum" which means "the best".
Answer:
The velocity of the bag will be 16.08 m/s
Explanation:
Given:
Mass of the astronaut, M = 124 kg
Mass of the bag, m = 10 lg
Initial speed of the astronaut with bag, = 1.20 m/s
Applying the concept of conservation of momentum
we have
(M + m) = Mv₁ + mv₂
here,
v₁ is the final velocity of the astronaut = 0
v₂ is final velocity of the bag
thus, on substituting the values, we have
(124 + 10)1.20 = 124 × 0 + 10v₂
or
v₂ = 16.08 m/s
Hence, <u>the velocity of the bag will be 16.08 m/s</u>
