Answer :
Answer:
change in speed) / (time for the change)
and the direction of the change.
Acceleration = (60 - 0) km per hour / 5 sec = 12 km per hour per second, east.
I hear teachers all over the country complaining about that ugly unit.
It has to be changed to a more familiar unit of acceleration.
(12 km/hour) x (1 hour/3600sec) = 12,000/3600 = 3-1/3 meter/sec.
His acceleration is 3-1/3 meters per second² .
Explanation:
a
Answer:
u=0
v=60 km/ hr
60 \times 1000 \\ 60 \times 60 = 1800
t =5
t = 5 \times3600 = 18000
a= ?
a = v - u \div t
= 1800 - 0 \div 18000 \\
