Explanation:
Given that,
The dimensions of a room are 16.40 m long, 4.5 m wide and 3.26 m high.
We need to find the volume of the room.
The room in the shape of cuboid whose volume is given by :
L,B,H are length, breadth and height of the room
So,
Hence, the volume of the room is
Answer
given,
angle with horizontal = 12°
constant speed with the slope = 1 m/s
Work on the skier to move 8 m = 900 J
a) Rope moved with constant speed
change in kinetic energy is equal to zero
work done by the force of the rope = 900 J
rate of force of the rope when skier move with
b) v = 1 m/s total time t = 8 s
Power =
=
= 112.5 W
c) v = 2 m/s total time t = 8/2 = 4 s
Power =
=
= 225 W
