a) Imagine that it's raining towards Ox, so x-component is 2
b) Rain towards Oy: 4.
c) V=(2, 4)
Answer: The car was moving with the speed of 14.13 m/s.
Explanation:
Length of the skid marks,d = 34 m
Mass of the car = 825 kg
Coefficient of friction = 
Velocity of the car after applying the brakes =v
Acceleration due gravity = 



v = 14.13 m/s
The car was moving with the speed of 14.13 m/s.
Answer:
Explanation:
Given
side of square shape 
Electric flux 
Permittivity of free space 
Flux is given by

where E=electric field strength
A=area
=Angle between Electric field and area vector



and Electric field by a uniformly charged sheet is given by

where
=charge density
