Question

If a particle is thrown upwards with a speed of 75 m/s find the distance travelled by particle in 8 sec.(1) Zero(2) 150 m(3) 2.5 m(4) 1.25 m​

Answer 1

Answer:

this is the height not distance covered

s = 286.4 m

Explanation:

u = 75 m/s                     &                    t = 8 s    

S = ?                              

s = ut + 1/2 at²

s = 75 x 8 + 1/2 x (-9.8) x 64

s = 600 - 313.6

s = 286.4 m
