G. A car covers the first half of the distance between two places at a speed of 40 km/ hr and the second
half at 60 km/hr, then can you evaluate the average speed of the car. Also Imagine a situation such that a
balloon is rising vertically from rest on ground with an acceleration of 4.9 m/s2 at the end of 4 second
then a stone is let fall from the balloon. Hence suggest the height of the balloon just when the stone is
dropped and also evaluate the velocity attain the balloon just when the stone is released. Also, you want
to suggest about the maximum height reached by the stone from ground level.

A toy car with a mass of 120 g moves to the right with a speed of 0.64 m/s. A small child drops a 36.0-g piece of clay onto the car. The clay sticks to the car and the car continues to the right. What is the change in speed of the car? Consider the frictional force between the car and the ground to be negligible.

When a car corners at speed one is relying on the friction between the tyres and the road to counter the centrifugal force tending to throw the car outwards. One way to reduce the dependence on friction is to ‘bank’ the corner. For a car travelling with a speed v entering a corner of radius r, show that the angle of the bank, θ, (measured from the horizontal) should satisfy tanθ = v2/(gr) if there is to be no reliance...

Measuring the distance between two trees, you measure that there are 75.5 steps between the two trees. Give an estimate of the unit of measurement of one step in meters and give an estimate of what you think its uncertainty is. Give the distance that separates the trees in meters as well as feet/inches and round to the correct amount of significant digits. What would you say are the uncertainties for the these two distances

The merry-go-round rotates counterclockwise with a constant angular speed u. The distance between the horse on the merry-go-round and the rotational center is r. (a) Find the position of the horse x and its velocity v, v(t) = d/dt x(t), as vector-functions of time. (b) Find the acceleration of the horse, a(t) = d^2/dt^2 x(t), as a vector-function of time. What is its direction (in comparison with the direction of x)? Now the same horse has a non-constant angular speed...
