Question

a ball starts from rest on a horizontal floor it is given an acceleration of 2 metre per second square it hits the wall at distance d from it in last second before it hits the wall it covers distance of 15 m.find d



dont write anything rubbish​

Answer 1

Answer:

Multiply the time by the acceleration due to gravity to find the velocity when the object hits the ground. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or 9.9 m/s.
