<u>Given that</u>
Speed = 60 Km/hr
In one hour, how much distance travelled by car
We know that
Distance = Speed × time
S = 60 × 1
S = 60 Km
In one hour car will travel 60 Km
W = mg = 350 newton
m = W/g = 350/9.8 = 35.71 kg
on mars
W = mg = 134 newton
g = W/m = 134/35.71 = 3.75 meters/second2
Answer:
9.5 seconds
Explanation:
You need to make the ending speed into meters per sec.
So it would be 120km/h = 33.33m/s
If the acceleration rate is 3.5m/s, then the final answer would equal to 9.5 seconds
Also btw rounding it up is a good idea too so 10 seconds if you round
The answer would be False, because theories change all the time.
