Remember the equation for acceleration.

a = (v - u ) / t

Were

a = acce;leration

v = final speed ( 20 m/s)

u = initial speed ( 0 m/s)

t = time ( 5 s)

Substituting

a = ( 20 m/s - 0 m/s) / 5s

a = 20m/s / 5s

a = 4 m /s^2

We know acceleration is the rate of change of velocity. now the velocity increases from zero to 20 m/s in an interval of 5 secs. therefore the acceleration is 4 m/s2.

How are constant speed and constant acceleration different?

There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.


How do you work out velocity when given acceleration and time?

Answer: v=u + at v (Velocity) = u (Starting velocity) + a (acceleration) x t (time) So, starting from stationary (u=0), the velocity is simply a x t e.g. if the acceleration is 5mph per second per second, after 10 seconds you would be travelling at 50mph. Answer: The above is for constant acceleration. In the case of variable acceleration, integration has to be used.

How can an object have a velocity of 0 m per s but still be accelerating?

^velocity* Consider an object that is travelling south at 10m/s. It accelerates north until it is travelling 10m/s. If we define south as negative, then it accelerates from -10m/s to 10m/s. -10 < 0 < 10, hence, it is travelling at 0m/s at some point.

Is it possible for two identical waves travelling in the soame direction along a string to give rise to a stationary wave?

No, it is not possible. For a stationary wave, two identical waves should travel in opposite direction along a string.
