Given: Force=8000N
displacement= 15 m
W=denotes Work
W= f × d
Substitute Values:
W = 8000 N × 15 m
= 120, 000 Nm
So, the elevator is doing 120, 000 Joule.
( Joule is the SI unit of work)
Speed of car = 130 km/hr = 130*5/18 = 36.11 m/s
Let the time taken for catching up be t,
Distance traveled by car = 36.11 t
Acceleration of police vehicle = 10.1 km/h/s = 10.1*5/18 = 2.81 m/
Distance traveled by police vehicle in time t =
Here u = 0, a = 2.81 m/
So, Distance = 0*t+
Comparing both the distances we have
So after 25.70 seconds police vehicle will catch car.
