(a) -1.208 m
The position of the particle at time t is given by
where:
is the initial position
is the initial velocity
is the acceleration
Substituting into the equation t=3.70 s, we find the position after 3.70 seconds:
(b) -0.838 m/s
The velocity of the particle at time t is given by:
where
is the initial velocity
is the acceleration
Substituting t = 3.70 s, we find the velocity after 3.70 seconds:
Answer:
Amplitude, A = 5 m
Explanation:
Let a progressive wave is given by equation :
.....(1)
The general equation of a progressive wave is given by :
....(2)
Here,
A is the amplitude of the wave
is the angular frequency
k is propagation constant
We need to find the amplitude of the wave.
If we compare equations (1) and (2), we find that the amplitude of the given plane progressive wave is 5 m.
Answer:
dog sleding ----> they do the work
Explanation:
The position vector of the bullet has components
The bullet hits the ground when , which corresponds to time :
The bullet travels 168 m horizontally, which would require a muzzle velocity such that
