Answer:
Uniform rectilinear movement (m. r. u.)
Explanation:
It is a continuous movement without acceleration, that is, it moves at a constant speed. The speed does not change over time, for this reason, there is no change in acceleration.
Vf = final velocity = 50/30 [km/s] = 1.67 [km/s]
Vo = initial velocity = 50/30 [km/s] = 1.67 [km/s]
The answer would be B: The ground exerts an equal force on the golf ball.
M1 v1 = (m1 + m2)v2.
All of the exponents should be lowered to the bottom right of the letters.
We know,
V= f× wavelength
10.5= f×0.15
f=10.5/0.15
f= 70 Hz
