A moving airplane dropped a cargo (ignore the effect of air resistance). If the plane from which the cargo was dropped was flying at a height of 600 m, and the cargo lands 300 m horizontally from the initial dropping point,

a. how fast was the plane flying when the cargo was released? (Vix=?)

b. what was the velocity of the cargo right before it hit the ground? (Vfy=?)

Solve for time first using this equation: t= √ 2y/ay

c. Draw a figure or diagram that illustrates the given problem.

A car starts from rest as accelerated uniformly at a rate of 2m/s^2 for 6s .it then maintains the constant speed for 30s,the breaks are then apllied and vehicle uniformly retands to rest in 5s .find the maximum speed reached at the total distance covered.

A tiny 0.8g ball carries a charge of magnitude 10μC. It is suspended by a thread in a
