Question: A car accelerates uniformly at a rate of 10m/s² from an initial velocity of 36km/hr for 30s. What is the covered distance during this period?

Answer:

Given data:

Acceleration of the car (a) = 10 m/s²,

Initial velocity of the car (u) = 36 km/h

Time of travelling (t) = 30 s


Step-1 To covert velocity in m/s from km/h.

As we know that 1 km/h = 1000/3600 m/s

Therefore,



Step-2 To determine distance travelled by the car within t = 30 s.
According to the equation of the constant acceleration motion. Distance travelled by the car can be written as,
 


Thus, the car will travel through 4800 m within 30 seconds.

Differences between Ideal and Real Fluids

A container, in the shape of a rectangle prism with dimensions l,w and h, is filled with an ideal gas and sealed. The average force exerted by the gas molecules on the bottom of the container is F. There are n moles of gas in the container and the temperature of the gas is T. What is h, the height of the container?
