Some gliders are launched from the ground by means of a winch, which rapidly reels in a towing cable attached to the glider. what average power must the winch supply in order to accelerate a 181-kg ultralight glider from rest to 25.7 m/s over a horizontal distance of 46.9 m? assume that friction and air resistance are negligible, and that the tension in the winch cable is constant.

Explanation:

Here we know that the glider is accelerated uniformly from rest to final speed of 25.7 m/s in total distance of d = 46.9 m

so we will have

d = 46.9

so for uniformly accelerated motion we have

now we will find the total work done given as change in kinetic energy

now power is given as

answer; ///i believe that the correct answer is (45*) at a 45 degree check first good

i need the answer to this too but idk it ; -;
