In an experiment, a variable, position-dependent force F(x) is exerted on a block of mass 1.0kg that is moving on a horizontal s

telo118 [61]

Answer: correct option is C

The function F(x) for 0 < x < 5, the block's initial velocity, and the value of Ff.

Step-by-step explanation:

The total work done = P.E + K.E

K.E = 1/2mv^2

The speed V depends on the position:

0 < x < 5

Also, since work done = F × distance x

The workdone also depends on F(x)

The net force = 0 that is

F + fr = 0

Where fr = frictional force.

Therefore the best option for the hypothesis of work done will be;

The function F(x) for 0 < x < 5, the block's initial velocity, and the value of Ff.

Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who

alekssr [168]

Answer:

They traveling at $0.37\ m/s$ in backward direction.

Step-by-step explanation:

Given mass of Ammy $m_1=55kg$

and velocity is forward at $v_1=3m/s$

Also, mass of Jenny $m_2=40kg$

Who is travelling in opposite direction $v_2=-5m/s$

Let velocity in forward direction is positive and velocity in backward direction is negative.

Also, velocity after crash is $v$

As they crashed into each other and they moved as one mass. We can apply principle of conservation of momentum.

Conservation of momentum says momentum before collision should equal to momentum after collision.

$m_1v_1+m_2v_2=(m_1+m_2)v$

$(55\times3)+(40\times(-5))=(55+40)v\\\\165-200=95v\\\\-35=95v\\\\v=\frac{-35}{95}=-0.368m/s$

So, velocity after collision $v$ ≅ $-0.37m/s$ is in opposite direction. That is the direction of Jenny.
