Solve the all parts of following problem:
Problem: A man is pulling a 5kg box of fish across a frozen frictionless pond. The rope he is pulling with makes an angle of 35 degrees with the horizontal.
Part A: If the magnitude of the pulling force is 25N, how quickly will the box accelerate along the ice?
Part B: After pulling for 5 seconds, the man immediately drops the rope. What speed does the box have at that moment?
Part C: After 15 seconds the events of part b. at what speed is the box moving?
I need help to find how quickly the box will accelerate along the ice.
