Question

If x=at +(1/2)bt^2, where x is in meters and t in seconds then unit of is

Answer 1

Answer:

The unit of a and b are m/s and m/s².

Explanation:

Given that,

....(I)

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.
