You are driving at 35 m/s east and notice another car that is initially located 462 m in front of you and is moving east at 25 m
GaryK [48]

The easiest way to answer this question is by realizing there are relating the velocities of the two cars. To tackle this problem, you have to understand the picture.  Car 1 travels at 35m/s and Car 2 travels at 25m/s.  Based on relative velocities, we can understand that Car 1 travels 10m/s faster than Car 2 every second.  So we can interpret Car 1's relative velocity to Car 2 as 10m/s.  Car 1 needs to travel 10m/s till a point of catching up to Car 2 which is 462m away.

v = 10m/s

d = 462m

v = d/t

(10) = (462)/t

t = 46.2s

So it takes 46.2 seconds for Car 1 to catch up to Car 2, but the question is asking how far does Car 1 travel to catch up.  So we have to use Car 1's velocity and not the relative velocity:

v = 35m/s

v = d/t

(35) = d/(46.2)

d = 1617m

Car 1 traveled a total distance of 1617m.

What is the mass of a large ship that has a momentum of 1.60x10^9 kg*m/s and is moving at a velocity of 10m/s?
Elden [556K]

Answer:

160000000 kg.

Explanation:

p=mv

p=1.6x10^9

v=10m/s

rearrange and substitute:

(1.6x10^9)=m(10)

m=(1.6x10^9)/10

m= 1.6x10^8 kg.

Determine the speed of a satellite relative to the indicated planet if the satellite is to travel indefinitely in a circular orb
frutty [35]

Answer:

v = √[ GM / (R + 160934.4 meters) ]

Explanation:

The speed of an object in a circular orbit (in meters per second) is

v = √(GM/r)

where

G = 6.6743e-11 m³ kg⁻¹ sec⁻²

M = the sum of the masses of the planet and the satellite in kilograms

r = the radius of the circular orbit in meters

If the planet's radius, R, is 100 miles, then

v = √[ GM / (R + 160934.4 meters) ]
