Physics, asked by reemaxyz729, 1 year ago

a object is thrown upward with velocity 20 metre per second find the height at when its strikes the ground and also time it will take

Answers

Answered by snehaa2830

key point - "velocity at max height is zero"

max height reached = 400/20 =20m

(using 3rd equation of motion)

time to go up = 20/10 =2s (using 1st equation of motion)

so time of flight = 2+2 =4s
