Δr1 = (600i − 230j) m, Δr2 = (420j) m, and Δr3 = (−285i + 137j) m. What is the displacement, in vector form?

An object moves with constant acceleration. At t= 2.50 s, the position of the object is x=2.00 m and its velocity is v= 4.50 m/s. At t= 7.00 s, v= -12.0 m/s. Find: (a) the positio...

Fleas have remarkable jumping ability. A 0.40 mg flea, jumping straight up, would reach a height of 40 cm if there were no air resistance. In reality, air resistance limits the hei...
