Explanation:
GIven data
mass of elevator = 2125 kg
Force= 21,750 N
Required
The maximum acceleration upward
F= ma
a= F/m
a=21,750/2125
a= 10.23m/s^2
Hence the acceleration is 10.23m/s^2

Answer:
b. 46 km/hr
Explanation:
Applying,
S' = d'/t'................... Equation 1
Where S' = Average speed of the bus, d' = Total distance covered by the bus, t' = Total time taken.
From the question,
d' = (100+55+75) km = 230 km
t' = (2+1+2) = 5 hours
Substitute these values into equation 1
S' = 230/5
S' = 46 km/hr.
Hence the correct option is b. 46 km/hr
