Answer:
Both objects travel the same distance.
(c) is correct option
Explanation:
Given that,
Mass of first object = 4.0 kg
Speed of first object = 2.0 m/s
Mass of second object = 1.0 kg
Speed of second object = 4.0 m/s
We need to calculate the stopping distance
For first particle
Using equation of motion
Where, v = final velocity
u = initial velocity
s = distance
Put the value in the equation
....(I)
Using newton law
Now, put the value of a in equation (I)
Now, For second object
Using equation of motion
Put the value in the equation
....(I)
Using newton law
Now, put the value of a in equation (I)
Hence, Both objects travel the same distance.
Answer:
Explanation:
To answer the question, we just need to consider the motion along the horizontal direction.
The component of the initial velocity of the ice skater along the x-direction is:
where u = 2.25 m/s is the initial velocity and 
is the angle.
The component of the final velocity of the ice skater along the x-direction is
where u = 4.65 m/s is the final velocity and 
is the angle.
The acceleration along the x-direction is given by
where
t = 120 s is the time
Substituting,
Answer:
The H-R diagram can be used by scientists to roughly measure how far away a star cluster or galaxy is from Earth. This can be done by comparing the apparent magnitudes of the stars in the cluster to the absolute magnitudes of stars with known distances (or of model stars).
The most essential while choosing the privilege PFD for a traveler is the information required for choosing right PFD for the traveler's body weight and trunk size.Note that the offspring of what age under 8 years old are required to wear legitimately secured PFD while on vessel unless in securely closed cabin.
