Answer:
The acceleration of the crate is
Explanation:
Recall the formula that relates force,mass and acceleration from newton's second law;
Then in our case, we know the force applied and we know the mass of the crate, so we can solve for the acceleration as shown below:
Answer:
Explanation:
given,
wavelength, λ = 50 cm
speed, v = 4 m/s
Amplitude, A = 5 cm
general equation of the wave along x- axis
sign is positive when wave is traveling in negative direction
now,
inserting all the values
Hence, the y-equation of wave is equal to
