g (15 points) Picture taken from problem 13-35. A 2000 kg truck is traveling at 25 meters/second. The driver suddenly hits the b

rakes, causing the truck to slide on the road. The coefficient of friction between the truck and the road is µk = 0.32. Determine the distance the truck slides. (Notice: the box is irrelevant in this problem)

Answer:

Δx = 3.99 m

Explanation:

To determine distance, use kinetic energy

will make it short and easy.  

KE=1/2mv2 and KE=Δxmgμ

 

Set the equations equal to each other

1/2mv2=Δxmgμ            (Note: The masses cancel )

 1/2v2=Δxgμ                  Solve for Δx

where g=9.8  

Δx=v2/(2gμ)                   Δx = 25 / (2 * 9.8 * 0.32)     Δx = 3.99 m

Please let me know if its correct, if not report it so we can correct it.

This problem is to let you practice using Newton's second law of motion:

Force = (mass) x (acceleration)

-- The airplane's mass when it takes off (before it burns any of its load of fuel) is 320,000 kg.

-- The force available is (240,000 N/per engine) x (4 engines) = 960,000 N.

-- Now you know ' F ' and ' mass '.  Use Newton's second law of motion to calculate the plane's acceleration.

Which force acts as an object to move it from rest or a constant straight line motion
sleet_krkn [62]

Answer:

The force is Inertia

Explanation:

The force that acts on an object to move it from rest or a constant straight line motion is known as Inertia.

In physics the above statement is governed by Newton's first law of motion which is also known as Law of Inertia.

This law states that, an object that is at rest will remain at rest and an object that is moving will continue to move in a straight line with constant speed, if and only if the net force acting on the object is zero.

This implies that, A stationary object will remain motionless if no force acts on it while a object with constant velocity will continue moving with constant velocity until a force acts on it (neglecting resistance from air and friction).

Two pendulum bobs have equal masses and lengths (8.100 m). bob a is initially held horizontally while bob b hangs vertically at
Karo-lina-s [1.5K]
Since both hv same mass and elsstic collision, so their velocity will exchange. Bob A will stop and bob B will move with speed of A just before the collision.

Speed will be = squreroot ( 2*g*L)

L is length of pendulum
