Answer:
A. 88,200 J
Explanation:
Given data,
The mass of the crate, m = 200 kg
The height of the shipping container, h = 45 m
The gravitational of a body is possessed by the body due to the virtue of its position.
The formula for gravitational potential energy is,
P.E = mgh joules
Substituting the values
P.E = 200 x 9.8 x 45
= 88,200 J
Hence, the gravitational potential energy of the crate is, P.E = 88,200 J
Answer:
a = 20.532 g
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s²
Magnitude of deceleration is 201.42 m/s²
g = 9.81 m/s²
Dividing a by g
a = 20.532 g
How about a carousel (merry go round).
For any one horse or rider, Speed is constant but direction keeps changing, so velocity does too.
Answer = 1000N
F = ma
M = 500kg
a= 2 m/s/s
Solve for F
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.
