A40 g super ball strikes a wall with a velocity of 10 m/s that is normal to the wall it bounces away at a velocity of 7 m/s so normal to the wall what is the boss change in momentum is the ball bounces last is. one seconds what is the force between the ball and the wall

The measurement of mass in motion is called momentum. The change in the momentum of the ball will be 0.68kgm/sec. While the force that acts on the body will be 0.68 N.

The measurement of mass in motion is called momentum. Momentum is equal to its mass multiplied by its velocity. Mathematically it is given as;

Momentum = Mass x Velocity

The given data in the problem is

ball mass ( m)= 40 g=0.040 kg

speed of the ball(v) = 10 m/s

rebound speed(V )= -7 m/s

The change in the momentum of the body is given by,

Δp = mv - mv'

Δp= 0.040 x 10 - 0.057 x (-7)

ΔP = 0.68 kg.m/s

Hence the change in the momentum of the body will be 0.68 kg.m/s.

Impulse is defined as the product of force and time interval of contact.

Hence the force that acts on the body will be 0.68 N.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

i had this question and the answer was 3.15 miles.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles
