What happens when force is applied in the direction of motion?

How is work done measured when, The force is inclined to the direction of motion of the body?

A 5.00-kg block of ice is sliding across a frozen pond at 2.00 m/s. A 7.60-N force is applied in the direction of motion. After the ice block slides 15.0 m, the force is removed. The work done by the applied force is

In the given table, Column I shows masses of the objects, Column II shows the initial and final velocity of the object after force is applied on it and Column III shows the time span for which force is applied on the object. Conditions for a motorcar with the force of 6000 N applied in opposite direction of motion are :

If the force applied on the object is in the direction of motion, the speed of the object .........
