A car drives on a road which begins flat...?

Question

A car drives on a road which begins flat, then goes up and over the top of a hill and then goes down into a dip and back up to level ground.

11) Compare the magnitude of the normal force acting on the car at each point:

Nflat > Ntop of hill > Nbottom of dip
Nflat > Nbottom of dip > Ntop of hill
Nbottom of dip > Ntop of hill > Nflat
Nbottom of dip > Nflat > Ntop of hill
Ntop of hill > Nbottom of dip > Nflat
Ntop of hill > Nflat > Nbottom of dip
12) If the car is moving at 30 m/s at the bottom of the dip, its mass is 800 kg, and the radius of curvature for the dip is 20 m, what is the normal force acting on the car in the dip.

10459 N
19344 N
28625 N
37190 N
43840 N
13) What is the acceleration of the car at the bottom of the dip?

0 m/s2
9.8 m/s2
35.2 m/s2
45.0 m/s2
54.8 m/s2
14) What is the minimum speed at the top of the hill (assuming R = 20 m here, too) for the car to leave the road?

10 m/s
12 m/s
14 m/s
16 m/s
18 m/s
15) What is the acceleration of the car if it just begins to leave the road?

0 m/s2
4.9 m/s2
9.8 m/s2
14.7 m/s2
19.6 m/s2

Answer 1

Stop trying to cheat on a test and answer it yourself !

Answer 2

Sounds like the car needs a new flux capacitor. Then it would disappear and your answer should be 0.

Answer 3

if you're stopped on a hill or one thing put on the handbrake as soon as you're in a position to head off placed the automobile in equipment including your hand at the handbrake as soon as you experience extremely of bite interior the grab launch the handbrake slowly and circulate off do no longer save your self in position making use of grab and accelerator balancing it may prevent in position and make it individual-friendly to head off yet you will put on out the grab
