What net external force is required to give a 27.6 kg suitcase an acceleration of 3.3 m/s^2 to the right?

Nearly all physics problems will use the unit m/s for acceleration explain why is not the unit given as m/s as it is for speed?

Peter found an amazing fact in an amusement park when he tried to ride the Magic Mountain Superman. Powerful magnets accelerate a car and its riders from zero to 45 m/s in 7 seconds. Suppose the mass of the car and riders is 5,600 kg.

The formula s = 16t2 gives the distance an object falls due to gravity, where s is the distance in feet and t is the time in seconds. how many feet will the object fall in 6 seconds?

Consider equal volumes (say 1 l of a given substance in the solid, liquid, and gas phases. arrange them in order of decreasing mass based on the trend for the average substance.
