Question

A car is running with the velocity of 72 km/h. What will be its velocity after 8 s if its acceleration is 5 m/s2?

Answer 1

Answer:

first change km/hr to m/s by dividing 72/3.6.

Explanation:

initial velocity=(72/3.6)

20#

total time taken=8s.

acceleration = 5m/s2.

then

final velocity=?

as we all know,

a=u-v/t

or,5=20-0/5

Answer 2

Answer:

32km|/h

Explanation:

Accodinng to formula,

v=u-at

Where u is present velocity.
