What force and acceleration would a proton experience if it has a velocity of 2. 106 m/s perpendicular to a magnetic field of 2.0 T? force: ________ N acceleration: _______ m/s2 Homework Equations F = ma Frictional force = uk(n) Acceleration=force divided by mass.

A baseball is hit with a horizontal speed of 16 m/s and a vertical speed of 19 m/s upward. What are these speeds 1 s later? horizontal speed 16 m/s vertical speed ? m/s I figured out that the horizontal speed would still be the same and it was. So i thought that the vertical speed...

mass x velocity 44kg x 8m/s= 352 30kg x 8m/s=240 352-240=112m/s didn't seem right but i thought i would try it anyways

i tried the linear momentum equation..mass * velocity and the answer was still incorrect

A woman with a mass of 44 kg runs at a speed of 8 m/s and jumps onto a giant 30 kg skateboard initially at rest. What is the combined speed of the woman and the skateboard? 44 kg / 8 m/s=5.5 30 kg / 8m/s=3.75 5.5+3.75=9.25m/s

thank you!

If the baseball (mass = 145 g) stays in contact with the bat for 0.08 s and leaves the bat with a speed of 68 m/s, what is the average force acting on the ball? F=ma a=68/.08= 850m/s^2 Average Force=850*145=123250N
