What is the acceleration of a bike that starts from rest and after 10s is traveling 20m/s?

Physics
1 answer:
kow [346]3 years ago
6 0

Answer:

10meter per second square

Explanation:

since the bike is from rest, the initial velocity is zero and the final velocity is 20m/s . so by formula a=v-u/t

a = 20-0/10

a = 2

A sled of mass m is coasting on the icy surface of a frozen river. While it is passing under a bridge, a package of equal mass m
sweet [91]

Answer:B

Explanation:

Given

mass of Sled is m

another package of mass m is thrown on it

Suppose u be the initial velocity of sled

conserving momentum

mu=2mv

v=\frac{u}{2}

where v is the final velocity

Initial kinetic energy =\frac{1}{2}mu^2

Final Kinetic Energy=\frac{1}{2}(2m)\cdot (\frac{u}{2})^2

Final Kinetic Energy=\frac{1}{2}\times \frac{1}{2}mu^2

Final kinetic Energy is half of initial

Plane-polarized light is incident on a single polarizing disk, withthe direction of E0 parallel to thedirection of the transmiss
Alenkinab [10]

Answer;

Cos²စ= I/Io

So

A. Cos²စ = 1/2.2

Cosစ= √1/2.2

စ = cos^-1 0.68

= 47.2°

B.

Cosစ = √1/5.2

စ = ,cos^-1 0.4385

= 64°

C.

Cosစ = √1/12

စ = cos^-1 0.2886

= 73.2°

6. A .25 kg arrow with a velocity of 12 m/s to the west strikes and pierces the center of a 6.8 kg target. a. What is the final
Alenkasestr [34]

Answer:

(a) the final velocity of the combined mass is 9.43 m/s

(b) the decrease in kinetic energy during the collision is 386.1 J

Explanation:

Given;

mass of arrow, m₁ = 25 kg

initial velocity of arrow, u₁ = 12 m/s

mass of target, m₂ = 6.8 kg

initial velocity of the target, u₂ = 0

Part (a)

From the principle of conservation of linear momentum;

Total momentum before collision = Total momentum after collision

m₁u₁ + m₂u₂ = v(m₁+m₂)

where;

v is the final velocity of the combined mass

25 x 12 + 0 = v(25 + 6.8)

300 = v(31.8)

v = 300/31.8

v = 9.43 m/s

Part(b)

Kinetic Energy, K.E = ¹/₂mv²

Initial kinetic energy =  ¹/₂m₁u₁² + ¹/₂m₂u₂²  = ¹/₂ x 25 x (12)² + 0 = 1800 J

Final kinetic energy = ¹/₂m₁v² + ¹/₂m₂v² = ¹/₂v²(m₁ + m₂)

                                                               = ¹/₂ x (9.43)²(25+6.8)

                                                               = 1413.91 J

Decrease in kinetic energy = Initial K.E - Final K.E

Decrease in kinetic energy = 1800J - 1413.91 J = 386.1 J
