What is the correct equation for calculating a time?
|
|
time = acceleration / change in velocity
|
|
|
time = change in velocity x acceleration
|
|
|
time = change in velocity / acceleration
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Acceleration is the change in velocity with respect to time and its formula is as follows: a = d v d t, where v is the velocity of the body and t is the time taken.
Detailed explanation-2: -Acceleration is defined as the rate of change of velocity, therefore, F=ma. Q.
Detailed explanation-3: -Best Answer Use v = u + a*t where v is final velocity (0 m/s here), u is initial velocity (4 m/s), a is acceleration (-9.81 m/s2) and t is time.
Detailed explanation-4: -a = (v f-v i) / t; a = 2 × (d-v i × t) / t²; a = F / m; 02-Feb-2023
