Answer:
<h2>3</h2>
Explanation:
Using the efficiency formula. Efficiency = MA/VR * 100%
MA = Mechanical Advantage
VR = velocity ratio =
Distance moved by effort = 4.5m
distance moved by load = 1.5m
VR = 4.5/1.5 =3
Assuming efficiency is 100% (since friction can be ignored)
100% = MA/3 * 100%
1 = MA/3
MA = 3*1
MA = 3
Mechanical Advantage of the ramp is 3
Answer:
x = 0.327 m
Explanation:
Block 2 of mass 1.00 kg is at rest
spring constant = 200 N/m
Block 1 of mass 2 kg moving at 4 m/s
m₁ v₁ = (m₁ + m₂)V
2 x 4 = (2 + 1) V
V = 2.67 m/s
loss of kinetic energy = gain elastic potential energy
x = 0.327 m
hence, the spring compressed distance is equal to x = 0.327 m
Answer:
<h2>2000 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 1000 × 2
We have the final answer as
<h3>2000 N</h3>
Hope this helps you
Everything in presence is moving. That is the most essential naturally visible thing to think about the universe. In this way, consider a youthful star and any sensible measure of material about it. Regardless of the possibility that it was by one means or another equally, arbitrarily separated in a circle about the youthful star and moving in any case, the star and its gravitational impacts will rule. So its immense mass turns in a given plane and its gravity field twists fundamentally spacetime in that plane and less so in whatever another plane. In any case, the development of the star drags the only things that are important around it step by step into its rotational plane.
Answer:
average speed, accelerated speed
Explanation:
Pace was first moving at 38 km/h which was his average speed but the fastest speed he went was 60 km/h so he accelerated.
