Block P of mass

2\,\text{kg}

lies on block Q of mass

5\,\text{kg}

. The surface between P and Q has coefficient of static friction

0.25

and coefficient of kinetic friction

0.20

. The horizontal surface under Q is smooth. A horizontal force of

15\,\text{N}

is applied to block P. a. Will block P slip over block Q? b. Find the acceleration of block P relative to the ground.
