Answer #1

Given,

mass, m = 55g = 0.055 kg

distance, d = 11 m

g= 9.8 m/s2

Let

v:final velocity

u:initial velocity = 0

Since it falls freely

solving for t

t = 1.5 sec

Now using

v= 14.7

Therefore, momentum = mass x velocity = 0.055 x 14.7 = 0.8085 kg⋅m/s

I hope this will help you. Have a good day. Please give a like. Thanks.

A 2300 kg car moving at an initial speed of 25 m/s along a horizontal road skids to a stop in 50 m. (Note: When stopping without skidding and using conventional brakes, 100 percent of the kinetic energy is dissipated by friction within the brakes. With regenerative braking, such as that used in hybrid vehicles, only 70 percent of the kinetic energy is dissipated.)

A model rocket is fired straight up from the top of a 55-m-tall building. The rocket has only enough fuel to burn for 3.0 s. But while the rocket engine is burning fuel, it produces an upward acceleration of 60 m/s2. After the fuel supply is exhausted, the rocket is in free fall and just misses the edge of the building as it falls back to the ground. Ignoring air resistance, calculate 1. Determine the height above the ground of...

1. A careless painter dropped a brush (with paint!) from a scaffold outside a building he's supposed to paint. You were just recording a selfie video across the street and caught the falling brush in your video. You used your physics skills to figure out the paint brush was falling at 4.0 m/s when it was just passing the top of a window that you estimated at 7.0 m above the ground. How long did it take the brush to...

1. Physics and astronomy student club has a recently established tradition of pumpkin drop, from the top of Wick Science Building to the "moat" below street level. Although the "experimental data" have not been made public, there have been rumors of the drop took 2.07 seconds, i.e. falling from rest with negligible air drag. Based on the rumor, how tall is the building from the "moat" to the roof? Ignore air drag or any rotation of pumpkins. Hint: You may...

She can do nothing to change the velocity at impact or the mass of the occupants or the characteristics of a vehicle hitting the barrier. The only thing she can change is the depth of the barrier to increase the time of deceleration. This is because _________ remains constant during the crash. a.Acceleration b.displacement c. Force d. Impulse...
