A radio wave has a frequency of 3,000,000 Hz and a wavelength of 100m. What is the speed?

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec
