(u) = 20 m/s
(v) = 0 m/s
<span> (t) = 4 s
</span>
<span>0 = 20 + a(4)
</span><span>4 x a = -20
</span>
so, the answer is <span>-5 m/s^2. or -5 meter per second</span>
Answer:
A= 61.35
B= -44.40
Explanation:
1. Using the components method we have:
Considering that the vector sum , then:
Then:
It means the value of x and y component is 0.
2. Determinate the equations that describe each component:
Form Eq. (1):
Replacing A in Eq. (2):
Replacing values of C, α and β in (4):
Replacing value of B in (3)
Answer:
v = 135.13 mph
Explanation:
Given that,
The race car was moving for 3.7 hours and during that time it traveled a distance of 500 miles south.
We need to find the speed of the car.
We know that,
Speed = distance/time
So,
So, the speed of the car is equal to 135.13 mph.
