Question

PLS HELP

Answer 1

7.5m/s

cuz the ball moves at a bad position making it so sideways and back to the front herr yerddd

Answer 2

Answer:

Part a)

Distance = 28.5 cm

Part b)

Displacement = 15.5 cm

Explanation:

Part a)

Total distance moved by the ball is given as total path length

so here we can say

distance moved in positive direction = 22 cm

distance moved in negative direction = 6.5 cm

total path length = 22 + 6.5 = 28.5 cm

Part b)

Displacement is the shortest distance between initial and final position

so we need to add vectorially

so here we have

displacement in positive direction = 22 cm

displacement in negative direction = 6.5 cm

Total displacement = 22 - 6.5 = 15.5 cm
