1. A race car accelerates at a rate of 15.6 m/s. If it starts from rest, how much time till it

Physics
1 answer:
musickatia [10]3 years ago
4 0

Answer: 5.79 s

Explanation:

Vs=0 m/s starting speed(from rest)

Vf=325 km/h= 325*1000/3600= 90.28 m/s

a=15.6m/s²

Using equation for acceleration  we can find out time :

a=(Vf-Vs)/t

t=(Vf-Vs)/a

t=(90.28 m/s-0m/s)/15.6 m/s²

t=5.79 s

A Navy vessel is traveling due north during wartime. A torpedo has been launched by an enemy directly toward the stern (rear) of
Anika [276]

Answer:

The correct option is;

B) No, the Navy vessel is slower

Explanation:

The speed of some torpedoes can be as high as 370 km/h. The average speed of a fast Navy vessel is approximately 110 km/h

Therefore, the torpedoes travel approximately 3 times as fast as the (slower) Navy vessel, such that the torpedo covers three times the distance of the Navy vessel in the same time and therefore, if the Navy vessel and the torpedo continue in a straight line (in the same direction) due north the vessel can not outrun the torpedo

Therefore, no the Navy vessel travels slower than a torpedo.
