A jeep starts from rest. If its velocity becomes 72 km/hr in 4 seconds. i. What is the acceleration of the jeep ?
[Ans: 5 m/s]
ii. What is the distance covered by jeep?
[Ans : 10 m]

See the answers below

Explanation:

To solve this problem we must use the following equation of kinematics.

But first we must convert the velocity from kilometers per hour to meters per second.

i)

Vf = final velocity = 20 [m/s]

Vo = initial velocity = 0 (stars from the rest)

a = acceleration [m/s²]

t = time = 4 [s]

ii)

Now we can calculate the distance with the following equation of the kinematics.

where:

x = distance covered [m]

when it gains or loses electrons

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
