A block of mass 1.58 kg which is initially at rest is acted upon by an impulse of 8.22 Ns due to a constant force. The impulse lasts for 0.187 s seconds and results in the mass moving at velocity v. The block then slides up a frictional ramp which has a length 2.00 m and a height 34.8 cm before colliding with a mass 3.16 kg . In this problem all horizontal surfaces are frictionless (only the incline is frictional). A) With what velocity does the mass move after the impulse acts upon it? v = m/s
B) What average force acts upon the mass during the impulse? Favg = N
C) If the block reaches the top of the incline with velocity 3.91 m/s , what is the coefficient of kinetic friction of the ramp? μκ =
D) If the 1.58 kg block collides and sticks to the 3.16 kg block, what final velocity results? Vfinal = m/s
E) How much Kinetic Energy was lost in the collision of the two blocks? KElost = ___ J

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
