A hockey puck with a mass of 0.18 kg is at rest on the horizontal frictionless surface of the rink. A player applies a horizontal force of 0.5 N to the puck. Find the speed and the traveled distance 5s
later.

Given :

A hockey puck with a mass of 0.18 kg is at rest on the horizontal frictionless surface of the rink.

A  player applies a horizontal force of 0.5 N to the puck.

To Find :

The speed and the traveled distance 5s  later.

Solution :

Acceleration is :

a = F/m

a = 0.5/0.18 = 2.78 m/s² .

Now, velocity after 5 seconds is given by :

v = 0 + 2.78×5 m/s

v = 13.9 m/s

Also, distance travelled :

Therefore, speed and the traveled distance 5 s later is 13.9 m/s and 34.75 m.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
