Answer:
1. The answer is that there will be more force with more speed.
2. less speed means less force.
3. And last, but certainly not the least, the less the mass has, the less the force will be, unless the object is moving at a high speed.
Explanation:
Answer:
Explanation:
Given:
Horizontal distance = 30 m
Note that Wavelength, lambda is the distance between two consecutive crests/troughs. Since,
One boat is at trough, the other is at crest.
The distance between a crest and a trough next to it = lambda/2
Complete cycles = 3 cycles
Time taken for the 3 cycles = 15 s
Vertical distance = 3.8 m
Wavelength, lambda = 2 × horizontal distance
= 2 × 30
= 60 m
Amplitude = vertical distance from the extreme loint to the mid point
= y/2
= 3.8/2
A = 1.9 m
In one cycle = 18/3
= 6 s/cycle
frequency, f = 1/T
= 1/6 = 0.17 Hz
speed,v = lambda × frequency
= 60 × 0.17
= 10 m/s
Increase because the mass of an object aligns with its weight
Answer:
The dog has more momentum than the pony.
Explanation:
To solve this problem, we must remember the formula for calculating momentum, which is given below:
momentum = p = m*v
where m represents the mass of the object and v represents the velocity of the object
Using this knowledge, let's calculate the momentum for the dog and the pony.
Dog: p = m*v = (2kg)*(41 m/s) = 82 kg*m/s
Pony: p = m*v = (75kg)*(1 m/s) = 75 kg*m/s
Since 82 > 75, we can conclude that the dog has more momentum.
Hope this helps!
Answer:
85 N
Explanation:
Given that crate mass = 20kg
Distance = 6m
Time = 3 seconds
Coefficient of kinetic friction = 0.3
We begin by calculating for acceleration
Which was gotten as 1.33 m/s sq
