1500 kg Peugeot car is traveling at 16.67 m s ⁻¹ and accelerates to 30.56 m s ⁻¹ for 2 minutes. Calculate the impulse of the car
Elis [28]

Answer:

2084 kg*m/s

Explanation:

Impulse is change in momentum

Mathematically;

Impulse, J= F*t=mΔv   where

F= ma = 1500 * { 30.56 - 16.67}/2*60

F= 1500 *0.11575

F=  174 N

J=F*t

J= 174*120*0.1

J= 2084 kg*m/s

A uniform electric field of magnitude 112 kV/m is directed upward in a region of space. A uniform magnetic field of magnitude 0.
notsponge [240]

Answer:

1.37\cdot 10^5 m/s

Explanation:

The beam of positively charged particles would not be deflected if the electric force acting on them is equal to the magnetic force:

F_E = F_B\\qE = qvB sin \theta

where

q is the charge of the particles

E is the magnitude of the electric field

v is the speed of the particles

B is the intensity of the magnetic field

\theta is the angle between the direction of v and B

Since the beam of particles travels perpendicular to the magnetic field, we have \theta=90^{\circ}, sin \theta=1. So, we can rewrite the equation as

v=\frac{E}{B}

where

E=112 kV/m = 1.12\cdot 10^5 V/m\\B=0.82 T

Substituting into the formula,

v=\frac{1.12\cdot 10^5 V/m}{0.82 T}=1.37\cdot 10^5 m/s

A dog runs at 35 m/s at 45 degrees N of E. What are its x and y components (all answers
pickupchik [31]

Answer:

its x and y component is 24.749m/s

Explanation:

Given

Speed of the dog = 35m/s

x component of the speed = xcos theta

y component of the speed = ycos theta

Given theta =45 degrees

x-component = 35cos45

x-component = 35(0.7071)

x-component = 24.749m/s

y-component = 35sin45

y-component = 35(0.7071)

y-component = 24.749m/s

Hence its x and y component is 24.749m/s
