Question

a ball is thrown vertically upwards with velocity 50m/s at t=0 . then find distance travelled from t=0 to t=8 s​

Answer 1

Explanation:

u=50m/s

a=-10

t=0

so,we know that,

s=ut+1/2at^2

s=50×0+1/2×(-10)×0

s=0

again,u=50m/s , a=-10 , t=8sec

s=ut+1/2at^2

s=50×8+1/2×-10×8^2

s=400-320

s=80m
