Question

An object is dropped on earth (g=10m/s/s (meters per second per second or m/s^2)) and it falls for five seconds draw a speed vs time graph

Answer 1

v = 10t

Step-by-step explanation:

The velocity of an object after time t is given by the equation
v(t) = u + at

Here u, the initial velocity is 0

a = acceleration = g = 10 m/s²

Therefore at any time,
v(t) = 0 + 10t

v = 10t

After 5 seconds, v = 10 m/s² x 5s = 50 m/s

The graph of this equation is given
