Answer:
We cannot tell from the information given
Explanation:
Given;
mass of the box, m = 5 kg
first force, F₁ = 10 N
second force, F₂ = 5 N
(I) Assuming the two forces are acting horizontally in opposite direction, the resultant force on the box is calculated as;
∑Fx = 10 N - 5 N
= 5 N
Apply Newton's second law of motion;
∑Fx = ma
a = ∑Fx/m
a = 5 / 5
a = 1 m/s² in the direction of the 10 N force.
(II) Also, if the two forces are acting in the same direction, the resultant force is calculated as;
∑Fx = 10 N + 5 N
∑Fx = 15 N
a = 15 / 5
a = 3 m/s²
Therefore, the information given is not enough to determine the acceleration of the box.
Answer:
she used force to swing her ball all way back
Explanation:
Answer:
56N
Explanation:
Given parameters:
Distance = 40m
Work done = 2240J
Unknown:
Force exerted = ?
Solution:
The work done on a body is the force applied to move a body through a certain distance.
Work done = Force x distance
Now insert the parameters and solve for the force
2240 = Force x 40
Force = 56N
Explanation:
Given that,
Let ABC is a triangle such that AB is perpendicular distance, BC is base and AC is the hypotenuse of triangle.
Let AB = 210 ft
AC = 90 + x
BC = x
To find :
The dimensions of the cornfield.
Solution :
Pythagoras theorem is used to find the value of x. It is given by :
On solving the above equation we find the value of x, x = 200 ft
So, BC = 200 ft
AC = 90 + 200 = 290 ft
So, the length, base and the hypotenuse of the triangle is 210 ft, 200 ft and 290 ft respectively.
