Find a function h(t) that gives the height of the rocket t seconds after startingits engines.What is the height of the rocket when it comes to a stop (i.e. when its velocityis 0)? (A decimal approximation is sufficient.) When coming in for a landing, a reusable rocket must fire its engines to slow itself down. Therocket is programmed to activate its engine at an altitude of 1500 meters, at which point itsvelocity will be – 150 m (negative since it will be moving down). t seconds after being activated,the engine imparts an acceleration of a(t) = 10vt m on the rocket.

Upload answer sheets A particle is moving along a plane curve and the position of the particle at any time t is (x, y). Let the equations of the motion dy of the moving particle be: +2x = 2 sin(t) cos(t), dx - dt dt 2y = 2 cos² (t)-1, t> 0. If at t = 0, x = 1 and y = 0, find the position of the particle at time t.
