would there be any accerleration or an instant change in speed?

It depends on the the frictional coefficient of the lorry and the elasticity
If the friction were very high, instantaneous acceleration. If the friction is 0, u will have no horizontal velocity .. u will just slide and fall off the lorry when the lorry passes the point.
If the elasticity of the lorry is very high, u will have instantaneous vertical acceleration while for low elasticity, u will have very little vertical acceleration and the lorry will bend downwards. You may assume the elasticity to be very high.

There would be acceleration in the horizontal due to gravity and then a huge instantaneous acceleration as the idiot hits the lorry, this question would probably be best analysed using collision and/or momentum theory. Because general equations of motion do not account for an instantaneous acceleration but rely on a constant acceleration.

You didn't say which direction the lorry was traveling. The definition of acceleration is the rate of change of velocity with respect to time. Velocity is a vector function, so if you change direction when you landed on the lorry, then by definition there is accleration.

Acceleration is the rate of change of velocity.Velocity is speed in a given direction.If you hit the train your velocity (speed and direction) would change so Yes there would be an acceleration.
Grizz...gravity acts vertically not horizontally.

At first there would be deaccerleration. Your body hitting the lorry would cause the lorry to slow down, but since the lorries mass and momentun is higher it would go on on its merry way.
You would be road kill. Answer your question? Or were you planning a James Bond?

Acceleration in a downwards direction (due to gravity). No acceleration in the horizontal direction.

By definition there is acceleration, but it would be very high.

If it did happen to you, that problem would be the least of your worries.

I think there would be a lot of pain.
