A5 kg frisbee is thrown from rest to a final speed of 12 m/s. What is the impulse of the frisbee?

lesya692 [45]

Answer:

60kgm/s

Explanation:

Given parameters:

Mass of frisbee = 5kg

Final speed = 12m/s

Unknown:

Impulse of the frisbee = ?

Solution:

The impulse of the frisbee is the same as the change in momentum.

It is given as:

Impulse = mass (Final velocity - Initial velocity)

Impulse = 5(12 - 0) = 60kgm/s

A train is moving with a constant velocity of 83 m/s in the easterly direction.

rodikova [14]

Answer:

166 m

Explanation:

t = Time taken

u = Initial velocity = 9.8 m/s

v = Final velocity

s = Displacement

g = Acceleration due to gravity = 9.80 m/s² = a

Equation of motion

$v=u+at\\\Rightarrow t=\dfrac{v-u}{a}\\\Rightarrow t=\dfrac{0-9.8}{-9.8}\\\Rightarrow t=1\ s$

Time taken to go up is 1 second and to go down will also be 1 second

Total time the rocket is up in the air is 2 seconds

$Distance=Speed\times Time$

$Distance=83\times 2=166\ m$

The distance the train will travel is 166 m
