A man starts running from his home towards east . After covering 60m ,he turns north and runs 80m. If he runs at uniform rate and covers the distance in 1 minute ,then what is its acceleration?

if he runs at a uniform rate the acceleration is zero.

To determine acceleration, displacement from the starting point is determined using Pythagoras theorem
c^2 = a^2 + b^2
c^2 = 60^2 + 80^2
c^2 = 3600 + 6400
C^2 = 10000 m
c = 100 m.
time (t) = 1 min (60 seconds)
velocity = displacement/ time
= 100/60
= 1.333 ms^-1

To find the acceleration of the man, we need to determine the change in velocity over time.

First, let's calculate the total displacement of the man using the Pythagorean theorem:

Displacement = √(60^2 + 80^2) = √(3600 + 6400) = √10000 = 100m

Since the man covers this distance in 1 minute, the velocity can be calculated by dividing the displacement by the time:

Velocity = Displacement / Time = 100m / 1min = 100m/min

Acceleration, on the other hand, is the change in velocity over time. Since we don't have information about any change in velocity, we can assume that the man starts at rest and accelerates to this velocity of 100m/min. Therefore, the acceleration is simply the velocity divided by the time:

Acceleration = Velocity / Time = 100m/min / 1min = 100m/min²

Hence, the man has an acceleration of 100m/min².

To determine the acceleration of the man, we need to know the change in velocity and the time it takes to change.

First, let's find the change in velocity. The man first runs towards the east for 60 meters and then turns north to run 80 meters. Since the two distances are perpendicular, they form the sides of a right-angled triangle. We can calculate the net displacement using the Pythagorean theorem.

Net displacement = √(east distance)^2 + (north distance)^2
Net displacement = √(60^2 + 80^2)
Net displacement = √(3600 + 6400)
Net displacement = √(10000)
Net displacement = 100 meters

Next, let's find the time it takes for the man to cover this distance. It is given that the man covers the distance in 1 minute.

Time = 1 minute = 60 seconds

Now we can calculate the acceleration using the formula:

Acceleration = Change in velocity / Time

The change in velocity is the final velocity minus the initial velocity. In this case, since the man is running at a uniform rate, the initial velocity and final velocity will be the same, as there is no change in speed. Hence, the change in velocity is 0.

Acceleration = 0 / Time
Acceleration = 0 / 60
Acceleration = 0 m/s^2

Therefore, the acceleration of the man is 0 m/s^2.
