As both marbles are free-falling under gravity both have the same acceleration, g or 9.81ms-2
arent u a science student? its simple. time,initial velocity,accelaration the formula is; v2=u2+2as here v is final velocity u is innitial velocity a is accelaration s will be3 the stopping distance okkkk!!
Accelaration= change in velocity/time taken OR Acceleration=final velocity- initial velocity/time taken
Retardation or deceleration is negative accelaration formula for finding retardation is same as that of accelaration: v-u/t, where v is the final velocity, u is the initial velocity and t is the time taken. eg- a bus is travelling at 20 m/s. Brakes are applied to stop the bus. The total time taken by the bus to stop is 2 s. Find its retardation. ans- v=0; u=20; t=2 accelaration= 0-20/2 a= -10 m's^2 retardation= 10 m/s^2 (because retardation is negative accelaration)
If they are instance variables the default initial value is 0. If they are method local variables, they are null and must be initialized to some value before they are used
The ENDPOINT
The origin.
When it's at its maximum height its speed will be zero.
accelaration is defined as the rate of change of velocity. Therefore the formula for acceleration is a =(Final Velocity - Initial Velocity) divide by the (change in time)

Another word for the first reason is "primary." This term indicates that it is the most important or initial rationale behind a decision or action. Other synonyms include "initial" or "principal."
do u know the answer
Those that are officially appointed to deal with the particular hazard. The initial organisation is quite often the police for instance.
