Question

if initial velocity of any object is 0 but it isn't written in question should i write this in given part of solution?​

Answer 1

Explanation:

yes why not. you can write initial Velocity is 0

Answer 2

Answer:

Formulas for Initial Velocity

Thus velocity at which motion start is the initial velocity. Obviously, this velocity at time interval t = 0. It is represented by letter u. Three initial velocity formulas based on equations of motion are given below,

• If time, acceleration and velocity are known. The initial velocity is formulated as

u =v – at

• If final velocity, acceleration, and distance are known then we can use the formula as:

u² = v² – 2as

• If distance, acceleration and time are known. Then the initial velocity will be computed as:

u= s/t-12at
