Question

An experiment involves gradually lifting of one end of air track so the height increases with time according to the h(t)=At where A=0.10m/s. The length of incline is 2 m.the glider is initially at rest at one end of air track. how much time It will take to reach the other end of the air track

Answer 1

As per the question,

the function of increasing height h(t)=At

A=0.1 m/sec

Length of the incline= 2m

So, velocity

$v=\dfrac{d h(t)}{dt}=A$ =0.1m/sec

Hence time taken =$\dfrac{2}{0.1}=20sec$
