Question

Q 13 of 60 A particle initially at x =10m, starts moving along the positive x-axis with an initial velocity of 40ms under the influence of an acceleration of 10ms directed along the negative x direction. Based on this information, answer the following questions. The particle reverses its direction of motion at time to from the start. Then​

Answer 1

Answer:

80 m

Explanation:

x = 10cm

u=40

a=-10

v=0

v=u+at

0=40-10t

t=4s.

v^2 = u^2 +2aS

0=1600-20S

S= 80m.
