Given data:
Initial velocity (u) = 30 m/s towards east
Final velocity (v) = 40 m/s towards north
Time taken (t) = 10 seconds
To find:
Average acceleration (a)
Explanation:
Step 1: Finding the change in velocity
The change in velocity (∆v) can be found by subtracting the initial velocity from the final velocity.
∆v = v - u
The initial velocity is towards east and the final velocity is towards north, which are perpendicular directions. Therefore, we can use the Pythagorean theorem to find the magnitude of the change in velocity (∆v).
∆v = √[(v_x)^2 + (v_y)^2]
Where,
v_x = magnitude of velocity towards east = 30 m/s
v_y = magnitude of velocity towards north = 40 m/s
∆v = √[(30)^2 + (40)^2]
∆v = √[900 + 1600]
∆v = √2500
∆v = 50 m/s
Step 2: Finding the average acceleration
The average acceleration (a) can be calculated using the formula:
a = ∆v / t
Substituting the values,
a = 50 m/s / 10 s
a = 5 m/s²
Therefore, the average acceleration of the body is 5 m/s².
Conclusion:
The correct answer is option D) 5 m/s².
Initial velocity (u) = 30 m/s towards east
Final velocity (v) = 40 m/s towards north
Time taken (t) = 10 seconds

∆v = √2500
∆v = 50 m/s
Step 2: Finding the average acceleration
The average acceleration (a) can be calculated using the formula:

a = 5 m/s²
