An object is initially moving at an unknown velocity. It accelerates at a rate of 2.0 m/s2 to a new velocity of 45 m/s in 10s. W

katrin2010 [14]

Answer:

Initial velocity=25m/s

Explanation:

acceleration(a)=2m/s^2

Final velocity(v)=45m/s

Time(t)=10seconds

Initial velocity(u)=?

V=u+axt

45=u+2x10

45=u+20

u=45-20

u=25m/s

A bolt is to be tightened with a torque of 7.0 N · m. If you have a wrench that is 0.55 m long, what is the least amount of forc

kodGreya [7K]

To solve this problem we will apply the given concept for torque which explains the relationship between the force applied and the distance to a given point. Mathematically this relationship is given as

$\tau = F*d \rightarrow F = \frac{\tau}{d}$

Where,

$\tau =$ Torque

F = Force

d = Distance

Our values are given as,

$\tau = 7.0Nm , d = 0.55m$

Therefore replacing we have that the force is

$F = \frac{7}{0.55}$

F = 12.72N

Therefore the least amount of force that you must exert is 12.72N

How are tensional forces created?

dezoksy [38]

Tensional forces are created on a piece of string or rope or anything similar when it is pulled tight from both sides, that is, when forces are acting on both ends, thus tightening it. <span>The tension force is directed along the length of the wire and pulls equally on the objects on the opposite ends of the wire.</span>
