A 15.4 kg block is dragged over a rough, horizontal surface by a constant force of 182 N acting at an angle of 24◦ above the hor
Dima020 [189]

Answer:

Explanation:

Considering Work done by friction is asked

Given

mass of block m=15.4\ kg

force F=182\ N

inclination \theta =24^{\circ}

block is displaced by s=57.6\ m

coefficient of kinetic friction \mu _k=0.135

Friction force F_r=\mu _kN

Normal reaction N=mg-F\sin \theta =15.4\times 9.8-182\sin (24)

N=76.9\ N

Friction Force F_r=0.135\times 76.9=10.38\ N

Work done by friction force

W=f_r\cdot s

W=10.38\times 57.6=597.92\ N

A car moves with an initial velocity of 19 m/s due north. (Part A) Find the velocity of the car after 5.6 s if its acceleration
galben [10]

Answer

Assuming

east is the positive x direction

north is the positive y direction

initial velocity , u = 19 j m/s

a) acceleration , a = 1.6 j m/s^2

Using first equation of motion

v = u + a × t

v = 19 + 5.6× 1.6

v = 28 j m/s

the velocity of the car after 5.6 s is 28 m/s north

b)

acceleration , a = -1.5 j m/s^2

Using first equation of motion

v = u + a × t

v = 19 - 5.6 ×1.5

v = 10.6 j m/s

the velocity of the car after 5.6 s is 10.6 m/s north

Covert 35000000 miles to meters and show how you got the answer?
Lina20 [59]

Answer:

56327040000 metres

Explanation:

1 mile =

1609.344 metres

35000000 miles = x meters

we represent x by the number of meters which the requested miles maps to

we cross multiply, so 1609.344×35000000 = 1 × x

x =56327040000 metres
