A small ball suspended from a string OA is set into oscillation. When the ball passes through the lowest point of the motion,
the string cut. If the ball is then moving with velocity 0.8 ms-1 at a height of 5 m
above the ground, find the horizontal distance travelled by the ball. (Assume
g= 10 ms-2 ).

Which of the following situations is impossible? a) an object has velocity directed east and acceleration directed east. b) an object has zero velocity but non-zero acceleration. c) an object has constant non-zero velocity and changing acceleration. d) an object has velocity directed east and acceleration directed west. e) an object has constant non-zero acceleration and changing velocity.

When using the scientist method, which step comes last?

An object dropped from cliff falls with a constant acceleration of 10 metre per second square find its speed of two seconds after it was dropped
