Given : A new sports car can accelerate from 0 to 96kph in 6.5 s.
To Find How quickly would you expect it to be able to accelerate from 80 kph to 112kph
Solution:
A new sports car can accelerate from 0 to 96kph in 6.5 s.
u = 0
v = 96 kph
a = 6.5 sec =6.5/3600 hrs
a = ( v - u)/t
=> a = (96 - 0 ) / ( 6.5/3600)
=> a = 3600 * 96 /6.5
accelerate from 80 kph to 112kph
=> u = 80
v = 112
a = 3600 * 96 /6.5
t = ?
112 = 80 + ( 3600 * 96 /6.5) t
=> 32 = (3600 * 96 /6.5)t
=> 13 / 6 * 3600 = t
= 13/6 secs
= 2.167 secs
