19. The velocity of an object at t = 0 is Vo = -4 m/s. It moves in a plane with constant
acceleration a =(3+8ì) m/s? What is its velocity after 1 s?
he acceleration a = 49. Its position after 3 sec
pls help me as fast as one can do!​

Answer 1

Answer:

Velocity is vector quantity, so is the acceleration, whereas speed is a scal. ... that a mass will continue to stay at rest or in a state of constant motion unless acted ... If one drops an object it moves towards earth with acceleration of 9.8 m/s2. ... So gravity on earth is 10m/s^2 because an object changes its speed by 10m/s
