A city bus travels 6 blocks east and 8 blocks north. Each block is 100 m long. If the bus travels this distance in 15 minutes, w

hat is the average velocity of the bus (m/s)?
Physics

Eddi Din [679]3 years ago
4 0

Answer:

1.56 m/s

Explanation:

For East direction, the 6 blocks is equivalent to 6*100=600 m

For West direction, 8 blocks is equivalent to 8*100=800 m

Speed is given by s=d/t where s is speed, d is distance covered and t is time taken

Total distance is 600+800=1400m

Time taken is 15 mins, converted to seconds will be 15*60=900 s

Speed, s=1400/900=1.5555555555555 m/s rounded off as 1.56 m/s

A motorcycle moving 18.8 m/s has<br> 57800 J of KE. What is its mass?
Brums [2.3K]

Answer:

m = 327.07 kg

Explanation:

Given that,

Kinetic energy of a motorcycle, E = 57800 J

Velocity of the motorcycle, v = 18.8 m/s

We need to find the mass of the motorcycle. The kinetic energy of an object is given by :

E=\dfrac{1}{2}mv^2

m is mass

m=\dfrac{2E}{v^2}\\\\m=\dfrac{2\times 57800 }{(18.8)^2}\\\\m=327.07\ kg

So, the mass of the motorcycle is 327.07 kg.

Your bike gets a flat tire. Its mass is 10 kg and you are able to accelerate your bike .5 m/s/s. What is the force on the bike..
STALIN [3.7K]

Answer:

50N

Explanation:

Given parameters:

Mass of the bike   = 10kg

Acceleration  = 5m/s²  

Unknown:

Force on the bike  = ?

Solution:

To solve this problem, we apply Newton's second law of motion.

  Force  = mass x acceleration

 Force  = 10 x 5 = 50N

radar devices are used by law enforcement to be sure that individuals are driving safely. they tell the officer how fast the veh
coldgirl [10]
The radar device determines the vehicle's instantaneous speed.

I would argue that the purpose of the device is not to determine
whether individuals are driving safely.  They only determine whether
individuals are driving within legal speed limits.  There's much more
to 'safe' driving than that, but the radar gun can't detect it.
