An electron has a mass of 0.511 MeV/c2. Calculate the speed, momentum, and total energy of a 0.991 MeV electron.

a person with a mass of 106kg has a weight of 1060n

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

that would be because of both gravity and friction. so     c

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
