A ball falls off a table and reaches the ground in 1s. Assuming g = 10 m/s², calculate its speed on reaching the ground and the height of the table.
we can list the given data as, initial velocity , u = 0m/s time t = 1s g = 10m/s² To f…
An object thrown vertically upwards reaches a height of 500 m. What was its initial velocity? How long will the object take to come back to the earth? Assume g = 10 m/s²
We can list the data as, height covered or distance covered, s = 500m g = 10m/s² To fi…
The mass and weight of an object on earth are 5 kg and 49 N respectively. What will be their values on the moon? Assume that the acceleration due to gravity on the moon is 1/6th of that on the earth.
As per the given data, we can list the data as, mass on earth , m = 5kg Weight on ear…
The radius of planet A is half the radius of planet B. If the mass of A is MA, what must be the mass of B so that the value of g on B is half that of its value on A?
As per the question we can list the data as To find - Solution - Using the formula …
An object takes 5 s to reach the ground from a height of 5 m on a planet. What is the value of g on the planet?
The given in the question can be listed as time t = 5s height h = 5m initial velocity…
A wave of frequency 500 Hz is travelling with a speed of 350 m/s. (a) What is the phase difference between two displacements at a certain point at times 1.0 ms apart? (b) what will be the smallest distance between two points which are 45º out of phase at an instant of time?
The given that can be listed is frequency n = 500Hz speed v = 350m/s we can find wave…
