A car is accelerated from 45 km/H to 65 km/h in 30 min. Find the acceleration of the car and the distance covered.

acceleration=40m/s² and distance is 27.5m

Step by step explanation:

(a)acceleration is given by:

a=v-u/t

v=65km/h,u=45km/h, t=30min which is ½hour

therefore a=65-45/½

a=40

the distance is given by:

S=ut+½at²

S=(45•½)+½(40)(½)²

S=27.5m

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms

unless if u could do my questions, if not i wouldn't want to
