For the work-energy theorem, the work done by the engine on the car is equal to the variation of kinetic energy of the car:
where m=1167 kg is the mass of the car,
is the initial speed and 
is the final speed.
Putting numbers into the equation, we find:
where m=1167 kg is the mass of the car,
Putting numbers into the equation, we find:
Answer:
94 kg or 921.6 N
Explanation:
The velocity function is . The acceleration function, a(t), is the time derivative of the velocity function.
At ,
Because the elevator is going upwards, the net acceleration, where g us acceleration of gravity.
The resultant weight is
Since the bathroom scale is graduated in kg, it's reading is
A
North and east are perpendicular directions hence we can use them as the basis of our coordinate system. The coordinates of this point can then simply be represented as
P = 1.4 N + 4.8 E (km)
The magnitude can be given by the right triangle formula :
P =
= 5 km
Direction = atan(N/E) = 16.3 deg north of east = 73.7 deg east of north
