Question

calculate the acceleration of a body which moves with 36 km\hr from rest in 5second please solve it in step by step​

Answer 1

Answer:

Explanation:

u = 36 km/hr = 36 * (5/18) = 10 m/s

v = 72 km/hr = 20 m/s

Using Newton's first eqn. of motion :

v = u + at

20 = 10 + a(5)

Hence a = 2 m/s²

Now the body stops in 20 seconds

Answer 2

Explanation:

36 *5/18 =10m/ s

Initial velocity =0m/ s

Final veliciy =10m/s

Time =5 s

now,Acceleration =V-u /t

or, a=10-0/5

or, a=2 m/ s2
