Question

A ball is thrown upward with a speed of 10ms-.calculate the speed of the ball after1sec

Answer 1

Answer:

Using the equation v = u + at, where ‘v’ is final velocity (what we want to calculate), ‘u’ is the initial velocity (10 m/s in this case), ‘a’ is acceleration (because the ball is being thrown up, acceleration due to gravity will be -9.8 m/s^2), and ‘t’ is the time (in this occasion it’s since the ball was thrown).

So plugging the numbers into the equation:

v = 10 + (-9.8)*(1)

v = 10 - 9.8

v = 0.2 m/s
