Question

A dog is standing in the bed of a pickup truck. The bed is coated with ice, causing the force of friction between the dog and the truck to be zero. The truck is initially at rest, and then accelerates to the right, moving along a flat road. As seen from a stationary observer (watching the truck move to the right), the dog

Answer 1

the dog will slid apposite to direction of truck movement.

Step-by-step explanation:

Lets take mass of dog = m kg

Mass of truck = M kg

Acceleration of truck =a
`m/s^2`

Given that friction force is zero between dog and the truck surface.

When truck will move forward then the force on truck = M .a (forward)

Then an pseudo force will act on the dog = m . a (in backward)

And there is no any friction force so the dog will slid apposite to direction of truck movement.
