The image contains a series of mathematical or physics-related problems. I'll transcribe the text so we can work through the problems.

1. A mass of 10 kg and a force of 20 N are connected to a block of 15 kg by a rope as shown. The surface is frictionless. What is the acceleration of the system?

2. A car moving with a velocity of 30 m/s applies the brakes and stops after 50 m. What is the deceleration of the car? 

3. A block of 5 kg is placed on a rough surface with a coefficient of friction \(\mu = 0.3\). Find the force required to move the block horizontally.

4. A 2 kg mass is hung from a spring balance. What is the reading on the spring balance when the mass is at rest?

5. If a force of 10 N is applied to a 2 kg mass, what will be the acceleration of the mass? What will be the velocity after 3 seconds if the mass starts from rest?
