A stone is thrown vertically upwards at A speed of 10ms^-1 from a height of 1.8m above ground level. Model the stone as a particle.
Create a fully labelled diagram Illustrating this situation.
Calculate the time when the stone is at its maximum height and find the time of flight.
Create sketches of the s-t v-t and a-t graphs of the stone’s motion until it hits the ground. Label the coordinates of all points(intercepts,maxima and minima)
Half a second after the first stone is thrown from the same place with a speed of U ms^-1 at an angle of a(alpha) to the horizontal where tan a=12/5. This stone hits the ground at the same time as the first.
Modelling this second stone as a particle, find U and the distance from the first stone that it lands.
I need help with the second part of the question that talks about half a second.
