Question

?

Answer 1

a) the velocity vector is tangent to the circle, and since the arm is moving clockwise, we can tell the direction

Answer 2

b) centripetal acceleration points from the car to the center as usual
c) a = v^2/r

Answer 3

a=26.8^2/14.6

Answer 4

good

d) 8g just means 8 * g where g is the universal gravity constant

Answer 5

anyway for e) just use the acceleration from d) to find the new velocity

Answer 6

sorry i had to go.... this for c right....a=26.8^2/14.6=49.19

Answer 7

good

units for acceleration are m/s/s as usual

Answer 8

D). 8 * 9.8=78.4

Answer 9

good

Answer 10

m/s?

Answer 11

the units are given in the problem

Answer 12

right m/s^2

Answer 13

good

Answer 14

okay now for E

Answer 16

yes, so i would use 78.4

Answer 17

yes

Answer 18

OKay so the equation would be 4?

Answer 19

it's the same centripetal motion problem so a = v^2/r

Answer 20

got it

Answer 21

78.4=v^2/8?

Answer 22

or would it b e equal to 8 maybe?

Answer 23

the radius is the same as the radius stated in c)

Answer 24

got it 78.4=v^2/14.6

Answer 25

good

Answer 26

=33.83

Answer 27

good, 33.83 m/s
