Question

A Honda fits accelerate from 0 to 60mph(27ms)in 9.5 sec. What is it's accelertaion?
supposed that the breaks are applied and it slows from 27ms to 18 ms while 45 m. what constant deceleration did it have?

​

Answer 1

Answer:

V^2=u^2 + 2*a*s

V is final velocity.

u is initial velocity.

a is acceleration.

s is distance.

27^2=9^2+ 2 ((27–9)/5) s

729=81 + 2 (7.2) s

648=7.2 s

90 m =s
