displacement = 6.5 m
speed =√2as
a =F/m
u have not given figure u find out net force from figure and then find accelration
substitute in above formula u ll get answer
now use formula
a =F/m
to get acceleration then v =u +at
gives the final velocity

An object of mass 6.50 kg undergoes a displacement S= 11.5 m i + 5.5 m j while it is being acted on by a net force F = 5.9 N i -2.2 N j. a) How much work is done on the object by the net force? b) If the object above starts from rest, what is its speed after it has undergone the displacement described above?

The (non-conservative) force propelling a 1.10 x 103-kg car up a mountain road does 6.50 x 106 J of work on the car. The car starts from rest at sea level and has a speed of 20.0 m/s at an altitude of 1.60 x 102 m above sea level. Obtain the work done on the car by the combined forces of friction and air resistance, both of which are non-conservative forces.

A 0.60 kg block rests on a frictionless horizontal countertop, where it is attached to a massless spring whose k-value equals 18.0 N/m. Let x be the displacement, where x = 0 is the equilibrium position and x > 0 when the spring is stretched. The block is pushed, and the spring compressed, until xi = −4.00 cm. It then is released from rest and undergoes simple harmonic motion. (a)What is the block's maximum speed (in m/s) after it is...

A block of weight w = 25.0 N sits on a frictionless inclined plane, which makes an angle θ = 28.0 ∘ with respect to the horizontal. A force of magnitude F = 11.7 N , applied parallel to the incline, is just sufficient to pull the block up the plane at constant speed. 1. The block moves up an incline with constant speed. What is the total work Wtotal done on the block by all forces as the block...
