An object weighs 2.50 kg. In time t, measured in seconds, the velocity of the object is given by bar(v)=(7.00t hati+2.00t^(2)hatj) m/s. At the instant the net force on the object has a magnitude of 35.0 N, what are the direction of the net force and the object's direction of travel ?

A force vec(F)=(3.00N)hat(i)+(7.00N) hat(j) + (7.00N)hat(k) act on a 2.00 kg mobile object that moves from an initial position of vec(r_(i))=(3.00m)hat(i)-(2.00m)hat(j)+(5.00m)hat(k) to a final position of vec(r_(f))+(5.00m)hat(i)+(4.00m)hat(j)+(7.00m)hat(k) in 4.00 s. Find the work done on the object by the force in the 4.00 s interval.

A force vec(F)= (3.00 N) hat(i)+(7.00 N) hat(j)+(7.00 N) hat(k) acts on a 2.00 kg mobile object that moves from an initial position of vec(d)_(i) = (3.00 m) hat(i)- (2.00 m) hat(j)+ (5.00 m) hat(k) to a final position of vec(d)_(f)=-(5.00 m) hat(i) + (4.00 m) hat(j)+ (7.00 m) hat(k) in 4.00 s. Find (a) the work done on the object by the force in the 4.00 s interval, (b) the average power due to the force during that interval, and (c) the angle between vectors vec(d)_(i) and vec(d)_(f) .
