Answer:
The force is
Explanation:
Given that,
Mass of car = 64 kg
Suppose, a 1400-kg car that stops from 34 km/h on a distance of 1.7 cm.
We need to calculate the acceleration
Using formula of acceleration
Where, v = final velocity
u = initial velocity
a = acceleration
s = distance
Put the value into the formula
We need to calculate the force
Using formula of force
Negative sign shows the direction of the force is in the direction opposite to the initial velocity.
Hence, The force is
The force of gravity increases with mass, but decreases with increasing distance between objects.
Answer:
2.3687599 m/s
0.91106 m/s
0.617213012 J
Explanation:
f = Frequency =
A = Amplitude = 0.13 m
k = Spring constant
m = Mass of object = 0.22 kg
Angular velocity is given by
Velocity is given by
Speed when it passes the equilibrium point is 2.3687599 m/s
Frequency is given by
x = Displacement = 0.12 m
In this system the energies are conserved
The speed when it is 0.12 m from equilibrium is 0.91106 m/s
The energy in the system is given by
The total energy of the system is 0.617213012 J
Answer:
Yes
Explanation:
The farther something is from the center of mass of an object such as a planet, the lower the gravitational force between them
F = GMm/d²
