Speed = distance / time
given:
distance = 225 km and time = 2.5 hours
so
speed = 225 / 2.5 = 90 km per hour
Answer:
Speed = 90 km per hour
        
             
        
        
        
Answer:
A.) Angle R, Angle S, Angle T
Step-by-step explanation:
It's a because it asked in order for an obtuse, an acute, and right. So in order it's R (for obtuse), S (for acute), and T (for right)

Answer:
The vertical component of the force correct to the nearest pound Is 
1352 pound 
Step-by-step explanation:
Kindly find attached for your reference 
This problem bothers on the topic of work energy and power 
Given data
Applied force = 3200 pounds
Angle of application = 25°
We know that the horizontal force =
F= 3200cos 25°
Hence the vertical component of this force = F= 3200sin 25
=3200*0.42261
= 1352.352
to the nearest pound
F = 1352pound
