Answer:
A- The elevator is moving upward at constant speed
Explanation:
am not sure of my answer but I think this is the most logical answer
Answer:
7.81 m/s
Explanation:
Given,
initial speed, u = 10.2 m/s
angle of inclination, θ = 40°
time, t = 2.12 s
Horizontal component of the velocity:
In projectile motion horizontal component of the velocity remain same at every point because there is no acceleration.
So, Velocity at the Pinnacle is equal to 7.81 m/s
Answer:
3.14 m/s
Explanation:
We are given that
Mass of object=1.1 Kg
Spring constant=160 N/m
a.We have to find the amount by which the spring is stretched from its unstrained length(it means x)
We know that F=kx ,
b.When an object is pulled straight down by an additional distance 0.26 m and released from rest.
x=0.26 m
We have to find the speed with which the object passes through its original position on the way up.
(Law of conservation of energy)
Substitute the values then we get
Hence, the speed of an object with which the object passes through its original position on the way up=3.14 m/s
If it is eight meters per second, and the total distance he has to travel is four hundred meters to complete the race, you divide the total length needed to travel by the average speed per second to see the amount of seconds required to complete the race at that speed.
8 meters per second: Speed of runner
400 meters: Total distance
400/8=50
50 seconds to complete the race at the eight of 8m/s.
Normally a storm surge.
