Question

A ball is thrown straight up from the ground with an unknown velocity. It reaches its highest point after 3.5 s. With what velocity did it leave the ground?

Answer 1

0.295 m

Step-by-step explanation:

Velocity of the wave= 1.3Kms-1= 1300ms-1

Frequency of the wave= 4.4MHz= 4400Hz

From

Velocity= wavelength × frequency

Wavelength= velocity/frequency

= 1300/4400

=0.295 m

hope this helps :)
