The equation Bold r (t )r(t)equals=(6 Bold sin t )Bold i plus (6 Bold cos t )Bold j plus (3 t )Bold k(6 sin t) i+(6 cos t) j+(3t) k is the position of a particle in space at time t. Find the particle's velocity and acceleration vectors. Then write the particle's velocity at t equals StartFraction 3 pi Over 2 EndFractiont= 3π 2 as a product of its speed and direction

f=ma newton

f=100x2.5=250n

i had this question and the answer was 3.15 miles.

d) 3.15 miles

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
