Question

afarl UVM Physics 11-Fall 2018 Cqulz chap3 Problem 3.10-Enhanced- with Feedback Find the &-and y-components of the vector d (3.0 km,28 loft of +y-axis). Express your answer in kilometers. Enter the z and y components of the vector separated by a comma km Submit Part B the z- and y-components of the vector (8.0 cm/s, -z-drection). Express your answer in centimeters per second. Enter the z and y components of the vector separated by a comma. cm/s Submit Request Answer Part C Find the a- and y-components of the vector a (19 m/s2 ,40 left of-v-axis). Express your answer in meters per second squared. Enter the z and y components of the vector separated by a comma.

Explanation / Answer

here,

a)

the x-component of d , dx = - d * sin(28)

dx = - 3 km * sin(28) km

dx = - 1.41 km

the y-component of d , dy = d * cos(28)

dy = 3 km * cos(28) km

dy = 2.65 km

b)

the x-component of v , vx = - v  

vx = - 8 cm/s

c)

the x-component of a , ax = - a * sin(40)

ax = - 19 m/s^2 * sin(40)

ax = - 12.2 m/s^2

the y-component of a , ay = - a * cos(40)

ay = - 19 * cos(40) m/s^2

ay = - 14.6 m/s^2
