Question

a table is thrown vertically upwards with a speed of 20 metre per second how height will it be after 2 seconds take ​

Answer 1

Answer:

We use the equation S = ut + 1/2 at²

u = 20m/s

t = 2

a = - 10 m/s²

S = 20×2 + 1/2 (-10)(2)²

S = 40 + (-20)

S = 20 m

Distance travelled will be 20 m.
