F1x + F2x = Rx
↓
Rx = F1x + F2x
↓
Rx = F1 cos45° + F2
↓
Rx = (50N)(cos45°) + 60N
↓
Rx = 95N
Similarly, if we sum all the y components, we will get the y component of the resultant force:
F1y + F2y = Ry
↓
Ry = F1y + F2y
↓
Ry = F1 sin45° + 0
↓
Ry = F1 sin45°
↓
Ry = (50N)(sin45°)
↓
Ry = 35N
At this point, we know the x and y components of R, which we can use to find the magnitude and direction of R:
Rx = 95N
Ry = 35N
Answer:
T = 850 N
Explanation:
given,
mass of billboard worker = 800 N
length of scaffold = 4 m
weight of the scaffold = 500 N
worker is standing at 1 m from one end.
Tension in the rope = ?
To calculate the tension in the string we have to balance the clockwise and counterclockwise moment of the system.
Weight of the worker and the weight of the scaffold will be in clockwise direction where as the tension will be in counterclockwise direction
now,
800 x 3 + 500 x 2 = T x 4
4T = 3400
T = 850 N
hence, tension in the rope is equal to 850 N
The source and the observer are moving towards each other. The observer is moving toward the source. The source is moving away from the observer

b) 
c) 
d) 
Explanation:
a) The initial vertical velocity is given by:
Where:
θ: 25°
v: is the magnitude of the speed = 23 m/s
b) The initial horizontal velocity can be calculated as follows:
c) The flight time can be calculated using the following equation:
Where:
x: is the total distance = 42 m
d) The maximum height is given by:
Where:
: is the final vertical velocity =0 (at the maximum heigth)
g: is the gravity = 9.81 m/s²
