valentinak56 [21]

Answer:

15193.62 m/s

Explanation:

t = Time taken = 6.5 hours

u = Initial velocity = 0 (Assumed)

m = Mass of rocket = 1380 kg

F = Thrust force = 896 N

v = Final velocity

a = Acceleration of the rocket

Force

F=ma\\\Rightarrow a=\frac{F}{m}\\\Rightarrow a=\frac{896}{1380}\\\Rightarrow a=0.6493\ m/s^2

Equation of motion

v=u+at\\\Rightarrow v=0+0.6493\times 6.5\times 60\times 60\\\Rightarrow v=15193.62\ m/s

The velocity of the rocket after 6.5 hours of thrust is 15193.62 m/s

Which device is designed to convert chemical energy into kinetic energy ?
irakobra [83]

Answer:

A.C. Generator

Explanation:

The device designed to convert chemical energy into kinetic energy is an A.C generator.

The generator uses fuel to cause the mechanical motion of the pistons in the device.

  • Chemical energy is a form of energy found between the bonds of compounds and molecules.
  • When the bonds are broken, energy is released.
  • The heat energy produced drives pistons and cause mechanical motion of the body.
  • This is a form of kinetic energy which causes the motion of a body.

a ball (mas .40) is initially moving to the left at 30m/s. After hitting the wall, the ball is moving to the right at 20 m/s. Wh
Step2247 [10]

Answer:

The impulse is -20kg m/s.

Explanation:

given mass of ball =  0.4 kg

The ball is moving towards left with the initial velocity = 30m/s

The momentum in left direction P1 = mv1

= (0.4)(30)

= 12 kg m/s

The given velocity towards right = -20 m/s ( negative sign shows inverse direction)

Momentum towards right, P2 = mv2

P2 = (0.4)(-20)

P2 = -8 kg m/s

The Impulse = change in momentum

= P2 –P1

= -8-12

= -20 kg m/s
