a car advertisement states that a certain car can be accelerated from rest to 70 km/h in 7 seconds find the cars adverage accele
ration
1 answer:
Step-by-step explanation:
v=70km/h
t=7 seconds
u=0
first change the unit km/h to m/s
1000km=1m
3600seconds=1h
v=70km/h ×1000km/3600s
v=19.44m/s
acceleration =final velocity(v)-initial velocity(u)/time
acceleration=19.44m/s-0m/s=19.44m/s
19.44/7=2.78 m/s

Answer:
b. 75
Step-by-step explanation:
a(n) = a1 + d(n-1)
a(n) = 8.5 + 3.5(n - 1)
a(20) = 8.5 + 3.5(20 - 1)
a(20) = 8.5 + 3.5(19)
a(20) = 8.5 + 66.5
a(20) = 75
