Answer:

1. The displacement is 427.2 km.

Explanation:

1. A = 150 km North

B = 400 km East

The net displacement is given by

R =\sqrt{400^2 + 150^2 }\\\\R = 427.2 km

Tom and Mary are riding a merry-go-round. Tom is on a horse about half way between the center and the outer rim, and Mary is on
iren2701 [21]

Answer:

Explanation:

Given

Tom is on half way between the center and the outer rim

Mary is on the extreme outer rim

Suppose \omega is the angular velocity of ride with radius of outer rim be R

\alpha =angular acceleration of Ride

At any instant both Tom and Mary experience the same angular speed

(b)Linear velocity at any instant

v_{Tom}=\omega \times R

v_{Mary}=\omeag \times \frac{R}{2}

Thus Tom has higher linear speed

(c) For radial Acceleration

a_r=\omega ^2\times r

a_{Tom}=\omega ^2\times R

a_{Mary}=\omega ^2\times \frac{R}{2}

Tom has higher radial Acceleration as it is directly Proportional of radius

A 250 kg flatcar 25 m long is moving with a speed of 3.0 m/s along horizontal frictionless rails. A 61 kg worker starts walking
Anna11 [10]

Answer:

x=31.09m

Explanation:

p1=p2

The momentum of flatcar and the momentum of the worker so

The velocity of the worker is:

m_{f}*v_{f}=m_{w}*v_{w}\\\\v_{f}=\frac{m_{f}*v_{f}}{m_{w}}\\v_{f}=\frac{61kg*3.0\frac{m}{s}}{250kg}\\v_{f}=0.732\frac{m}{s}

The total motion has a total velocity and is

Vt=v_{w}+v_{f}\\Vt=0.732\frac{m}{s}+3.0\frac{m}{s}\\Vt=3.732\frac{m}{s}

The time the worker take walking is

t=\frac{x}{v_{w}}\\t=\frac{25m}{3\frac{m}{s}}=8.33s

Now the total time and the total velocity determinate the motion of tha flatcar how far has moved

x=t*Vt\\x=8.33s*3.732\frac{m}{s} \\x=31.09m

The Kentucky Derby is a 1¼ mile race. Mandaloun ran it in 1.52 minutes. Hot Rod Charlie ran at a speed of .79 miles per minute.
artcher [175]

Answer:

Mandaloun won the race.

Explanation:

First, we will calculate the time taken by the Hot Rod Charlie:

s = vt\\t = \frac{s}{v}

where,

t = time taken by Hot Rod Charlie = ?

s = distance covered = 1.25 miles

v = speed of Hot Rod Charlie = 0.79 miles/min

Therefore,

t = \frac{1.25\ miles}{0.79\ miles/min} \\t = 1.58 min

Since Hot Rod Charlie took more time (1.58 min) than the Mandaloun (1.52 min).

<u>Therefore Mandaloun won the race.</u>
