A block of mass 4 kg is resting on a horizontal surface. Calculate the normal force acting on the block when a force of 10 N is applied horizontally, considering the coefficient of static friction is 0.5.
💡 Hint: Remember, normal force balances the gravitational force on a flat surface.
A spring is compressed by 0.1 m and has a spring constant of 200 N/m. How much force is exerted by the spring?
💡 Hint: Use the formula for the spring force.
