Answer:
Yes it will be changed
Explanation:
Lifting up requires potential energy while dropping down requires kinetic, both will have different equations
Answer:
These parts of the force are called the components of the force. The component that pushes right or left is called the x-component, and the part that pushes up or down is called the y-component. Mathematically, the components act like shadows of the force vector on the coordinate axes.
Answer:
steal and wood depends on the type, since there are some that are more than steel and on type of wood when translated is literally called axe breaker
Explanation:
e
Answer:
0.35
Explanation:
According to Newton's second law;
\sum Fx = ma
Fm - Ff =ma
Fm is the moving force = Wsin theta
Fm = 4(9.8)sin55
Fm = 32.1N
Ff is the frictional force = nmgcos theta
Ff = n(4)(9.8)cos55
Ff = 22.48n
Acceleration a = 6.0m/s²
Substitute the given values into the formula and get the coefficient of friction
32.11-23.48n = 4(6)
32.11-24= 23.48n
8.11 = 23.48
n = 8.11/23.48
n = 0.35
Hence the coefficient of friction is 0.35
