## Repeat Exercise 5.18 with the contestant pulling the block of ice with a rope over his shoulder at the same angle above the horizontal as shown in Figure 5.23(b).

Expert Solution
To determine

(a)

The minimum force must exert to get the block moving

### Explanation of Solution

Given info:

Mass of the block, m=45kg

Diagram of the block

Figure.1

Formula used:

For a stationary object algebraic sum of all the forces in a direction must be zero.

Fx=0,&Fy=0

Calculation:

The weight of the block will act in downward direction

W=mg=45×9.81=441.45N

Consider the free body diagram of the block

Figure.2

The normal force on the lake by the block is

N=mgFsin25οN=441

Expert Solution
To determine

(b)

Acceleration of the block once it start moving
