141705 A car starts from rest and accelerates at \(5 \mathrm{~m} / \mathrm{s}^{2}\). At \(=4 \mathrm{~s}\), a ball is dropped out of a window by a person sitting in the car. What is the velocity and acceleration of the ball at \(t=6 \mathrm{~s}\) ? (Take, \(g\) \(=10 \mathrm{~m} / \mathrm{s}^{2}\) )

141706 A stone is dropped from the top of a building. When it crosses a point \(5 \mathrm{~m}\) below the top, another stone starts to fall from a point \(25 \mathrm{~m}\) below the top. Both stones reach the bottom of building simultaneously. The height of the building is

141707 A hiker stands on the edge of a cliff \(490 \mathrm{~m}\) above the ground and throws a stone horizontally with and initial speed of \(15 \mathrm{~m}^{-1}\) The speed with which it hits the ground is

141708 A body initially lying at a point \((3,7)\) starts moving with a constant acceleration of \(4 i\). Its position after 3 seconds is
