Answer:
if there is no friction in a simple machine, work output and work input are found equal in that machine
Explanation:
A car with a velocity of 22 m/s is accelerated at a rate of 1.6
for 6.8s has the final velocity t be 32.88 m/s.
The acceleration means the amount of velocity changing per unit time.
The given data:
initial velocity, u = 22 m/s
time, t = 6.8 s
acceleration, a = 1.6 
We will be using the equation of motion:
v = u + at



The final velocity become 32.88 m/s.

Good i’m tired how about you
Any change in the speed or direction of motion is called "acceleration". You'll hear "deceleration" used for slowing down but that's not technically correct.
