HELP PLEASE Assuming equal rates of acceleration in both cases, how much farther would you travel if braking from 56 mi/h to rest than from 28 mi/h
a 3.2 times farther
b 4.8 times farther
c 4.0 times farther
d 5.2 times farther

(c) is the correct option.

Explanation:

Given that,

Initial velocity, u = 56 mi/h and 28 mi/h

Final velocity, v = 0

It is coming to rest it means it is under deceleration. So, it will be (-a). Using the third equation of motion as folows :

So,

Also,

Dividing equation (1) by (2)

So,

So, we will travel 4 times farther if  braking from 56 mi/h to rest than from 28 mi/h.

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
