Explanation: Frequency = Wave speed divided by wavelength.
a = acceleration of the bank cart = 4 m/s²
m = mass of the bank cart = 8000 kg
F = net force on the cart
According to newton's second law , Net force is the product of mass of the object and the acceleration of the object.
Net force = mass x net acceleration
hence Net force acting on the cart is given as
F = ma
F = 8000 x 4
F = 32000 N
hence the net force acting on the cart comes out to be 32000 N
