Question

1. A ball is acted upon by the following velocities
i) 3 m/s due east
ii) 11 m/s due south
111) 5 V2 m/s due north - east
Find the magnitude of the resultant velocity?​

Answer 1

Answer:

ii).11m/s due south.✓

Explanation:

hope it helps you a bit

by and have a nice day .

Answer 2

Answer:

The v arious velocities acting on the ball are shown in Fig. 2 (c ) .59 (a0.

<br> due East,

due South an

vec (OS) =5 sqrt 2 ms^(-1)

45^(0)

vec (OS)

5 sqrt 2 cos 45 ^(0) =5 ms^(-1)

5 sqrt 2 sin 45^(0) =5 ms^(-1)

A= 3+ 5 =8 m//s

vec (OP)'

B=11 -5 =6 m//s
