Force = mass * acceleration. Therefore, given the force of 120 N and the mass of 46 kg:
120 N = 46 kg * acceleration
120 kg-m/s^2 = 46 kg * acceleration (in m/s^2)
acceleration = 120/46 = 2.61 m/s^2
That's true.
I have a hunch that there definitely IS a change of phase at every reflection.
Answer:
1.9311 m/s
168.86792 N
Explanation:
v = Final velocity
m = Mass of truck =
s = Displacement = 26.5 m
Work done is given by
The speed is 1.9311 m/s
Work done is given by
The horizontal force is 168.86792 N
Answer:
Explanation:
Given
Ray of light incident on plane making an angle of with normal
Thus incident angle
So according to the law of incidence is equal to angle of reflection
thus
and angle between mirror and reflected ray
If the boy started at rest then its speed would be equal to 4.5 m/s squared.
