Velocity =
(displacement)/(time for the displacement), in the direction of the displacement.
Displacement = 8 m south
Time for the displacement = 4 seconds
Direction of the displacement = south
Velocity (8 m south) / (4 seconds), to the south
Velocity = 2 m/s, toward the south

Answer:
a) 400.4Joules
b) 262.69Joules
Explanation:
Work is said to be done if the force applied to an object cause the object to move through a distance
Workdone = Force × Distance
Given
Force = 76N
Distance= 5.2m
Work done = 77 × 5.2
Work done = 400.4Joules
b) If the force is exerted at an angle of 41°
Work done = Fdsin theta
Work done = 77(5.2)sin41
Work done = 400.4sin41
Work done = 262.69Joules
