Question
Map sapling 1leamig action figure is placed on a toy car which is initially at rest. Then the action figure moves through 4 time ntervals: 1)the car ihushed until it hits a wall, 2) then the action figure slides down a ramp. 3) flies off of the ramp and hits a wall at the peak of its trajectory momentarily coming to a complete stop, and finally 4) falling into the toybox and coming to rest. Assume that all surfaces except the wall have non-zero coefficients of static and kinetic friction. For each time interval, including the endpoints, determine whether the total work done on the action figure by gravity g normal forces N and friction (D is positive, negative, or zero. Neglect drag. Incorrect. While there is no normal force acting on the action figure while it flies , = 0 through the air, there is a normal force once the figure comes in contact with the wall.

Here ,
1) the car is ambushed untill hits a wall
Wg = 0
WN =0
Wf > 0
2)
when the figure slids down the ramp
Wg > 0
WN = 0
Wf < 0
3)
when it flies off the ramp
Wg < 0
WN = 0
Wf = 0
4)
for the action figure into the toybox
Wg > 0
WN = 0
Wf < 0
