A ball is thrown vertically upwards with velocity 50m/s at t=0. Find the distance travelled from t=0 to t=8s

Answer»

Answer:

80M

Explanation:

Velocity of the BALL = u=50m/s  (Given)

Time = t = 0 (Given)

Distance travelled from t = 0 to t = 8 - ?

a = -10

According to the SECOND equation of motion -

s = ut+1/2at²

Thus, SUBSTITUTING the value -

s = 50 × 0 + 1/2 × (-10) × 0

s = 0

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

 s = ut+1/2at²

Thus, substituting the value -

s = 50 × 8 + 1/2 × -10 × 8²

s = 400-320

s = 80

Thus, the distance travelled from t = 0 to t = 8s is 80m.
