1)
S₁ = V₁*t = 75*1,7 = 127,5 km
2)
S₂ = V₂*t = 91*1,7 = 154,7 km
I might be wrong but I’d say the first one
Answer:
•when a food service worker touches food
Explanation:
The worker is physically putting his hands on the food, therefore contaminating it which whatever’s on his hands
-YW!! <33
Answer:
The free body diagram is attached.
Explanation:
A force of 31[N] to the east, the second force goes to the south and it is equal to 28[N], the third force goes to the west and it is equal to 39 [N].
We can consider the crate as a particle. And all the forces are acting over the particle.
Answer:
3.13cm/s²
Explanation:
Given
Initial velocity u = 3.5cm/s
Final velocity v = 8.2cm/s
Time t = 1.5secs
Required
Acceleration of the cart a
To get that, we will use the equation of motion
v = u+at
Substitute the given parameters
8.2 = 3.5+1.5a
1.5a = 8.2-3.5
1.5a = 4.7
a = 4.7/1.5
a = 3.13cm/s²
Hence the acceleration to the cart is 3.13cm/s²
Answer:
displacement will be 83km from the marker that reads 249km.
