Help Plz ASAP Tom lifts a carton of mass 4 exerting a force of 60 upward. What is the acceleration of the carton after 4 seconds? Is the acceleration constant during these 4 seconds? What is the velocity of the carton at the end of the 4 seconds?

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
