Answer:
66m/s
Explanation:
because 10 meters/per second is going to be 22 mph/35 km, and 20m/s is 44 mph/70 km and in 3 seconds it would boost its mph/km(m/s) to 66 only because from 22 mph to 44 mph is 22 but 44/22 = 22, however you have top multiply that by 3 seconds which will coem out to 66 m/s, mph, km.
Answer: 3.33m/s²
Explanation:
Acceleration = rate of change in velocity with time
Acceleration = change in velocity / time
Initial velocity (u) = 10 m/s
Final velocity (v) = 20m/s
time (t) = 3s
a = V - U / t
a = (20 - 10) / 3
a = 10 / 3 = 3.33m/s²
