Answer:
The smallest distance the student that the student could be possibly be from the starting point is 6.5 meters.
Explanation:
For 2 quantities A and B represented as
and
The sum is represented as
For the the values given to us the sum is calculated as
Now the since the uncertainity inthe sum is
The closest possible distance at which the student can be is obtained by taking the negative sign in the uncertainity
Thus closest distance equals meters
Answer:
The horizontal component of the force exerted by Marcie is 25 N
Explanation:
Lets explain how to solve the question
Marcie shovels snow after a storm by exerting a force of 32 N on her
shovel at an angle of 50 degrees to the vertical
We need to find the horizontal component of the force exerted by Marci
The force direction is 50° to the vertical means
→ tan(50) = , where x is the horizontal component
of the force and y is vertical component
→ tan(50) =
By comparing between the two expressions of tan(50)
→ The horizontal component is Fx = F sin(50)
→ The vertical component is Fy = F cos(50)
We need the horizontal component
→ F = 32 N
→ The horizontal component = 32 sin(50) = 24.51 N ≅ 25 N
