Question

racing car initially at rest picks up a velocity of 180 kilometre per hour in 4.5 second calculate acceleration​

Answer 1

Answer:

acceleration = 11.111 m/s^2

Explanation:

According to the question;

initial velocity( u) = 0 m/s

final velocity ( v) = 180 km/h = 50 m/s

time ( t) = 4.5s

According to Newton's first equation of motion

acceleration =( v - u )/t

= 50-0/4.5

= 50/4.5

= 11.111 m/s^2
