Question

In a equation of motion - y=at+bt^2 represent the quantity y, a and b with it's SI unit respectively.

Answer 1

Answer:

Here, x =meters

t = seconds

From equation (I)

The dimension of x= L

The dimension of  t = T

The dimension formula of a is

The unit of a is m/s.

Again, from equation (I)

The dimension formula of b is

The unit of b is

Hence, The unit of a and b are m/s and m/s²

Answer 2

Answer:

s=ut+1/2at^2

Explanation:

s=distance covered=meter

u=initial velocity=m/s

a=acceleration=m/s^2

t=time=second
