Question

A 153 (one hundred and fifty-three) cheetah is running toward east with a speed of 80.0 km/h, where is attaches and holds onto a 45.0 kg gazelle who was running toward north at 63.0 km/h. What is the velocity (magnitude and direction) of the cheetah/gazelle system immediately after the attack?

Answer #1

Kindly like the answer if it is correct.

A 89.5-kg fullback running east with a speed of 5.05 m/s is
tackled by a 95.5-kg opponent running north with a speed of 3.10
m/s.
(a) Explain why the successful tackle constitutes a perfectly
inelastic collision.
(b) Calculate the velocity of the players immediately after the
tackle (I HAVE THE ANSWER TO B)
magnitude: 2.91
?direction: 33.25
m/s
north of east
(c) Determine the mechanical energy that disappears as a result of
the collision.
J
Account for the missing energy....

I ONLY NEED PART B ANSWERED
A 77.0-kg fullback running east with a speed of 5.40 m/s is
tackled by a 79.0-kg opponent running north with a speed of 3.00
m/s. (a) Explain why the successful tackle constitutes a perfectly
inelastic collision. ___________________
(b) Calculate the velocity of the players immediately after the
tackle.
magnitude=_____ m/s
direction=______ ° north of east
HINT: Find the total momentum of the two players before the
collision and use conservation of momentum to find...

25.) Suppose you are traveling in a bus at highway speed on a
nice summer day and the momentum of an unlucky bug is suddenly
changed as it splatters onto the front window. a) Compared to the
force that acts on the bug, how much force acts on the bus. (more)
(the same) (less)
b) Although the momentum of the bus is very large compared to
the momentum of the bug, the change in momentum of the bus compared
to...

It is generally a good idea to gain an understanding of the
"size" of units. Consider the objects and calculate the kinetic
energy of each one.
