The distance traveled by pendulum, in one back-and-forth swing is 75.75 inches.
The period of pendulum can be calculated by
Where,
- period
- length = 12 inches
- gravitational acceleration = 
Put the values,
Now, the angular displacement of the pendulum can be calculated by,
Where,
- amplitude
- angle = 
- angular displacement = 
= 2.866 m
Put the values and calculate for ,
Therefore, the distance traveled by pendulum, in one back-and-forth swing is 75.75 inches.

Answer:
Explanation:
The thermal efficiency of a Power cycle 
where;
--- (1)
---- (2)
The coefficient of performance is:
let replace the value of in the above equation then;
The
On the other hand, the heat pump
By replacing equation (1) into the above equation; we have:
t
Explanation:
Given
Mass (m) = 1200 kg
Acceleration (a) = 3 m/s²
Force (F) = ?
We know
F = m * a
= 1200 * 3
= 3600 Newton.
Therefore the force acting on the car is 3600 Newton.
