A cat chases a mouse across a 0.98 m high
table. The mouse steps out of the way, and
the cat slides off the table and strikes the floor
1.0 m from the edge of the table.
The acceleration of gravity is 9.81 m/s
2
.
What was the cat’s speed when it slid off
the table?
Answer in units of m/s

A ball at the end of a string is swung in a horizontal circle above a person's head at a speed of 2.0 m/s. Is the ball undergoing uniform motion?

Although the Cheetah is, without a doubt, the fastest ground runner, it can only maintain an incredible speed of 110 km/h for about 175 meters.
a) how long is that?
b) If a cheetah is in chase after a gazelle running at 50 km/h, how far should it be from its prey to guarantee a fruitful chase? Assume both maintain constant speeds during chase.

A car of 1000kg increases its speed from 10m/s to 20m/s, While moving 500m up in a road inclined at an angle x to the horizontal where sin x is equal to 1/2.
There is a constant resistance to motion of 300N. Find the driving force exerted by the engine assuming that it is constant(g=10 meter per second squared)

Show that numbers of the form a squared plus b squared, where a and b are integers are closed Under multiplication

A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 44.1 m/s2 . The acceleration period lasts for time 8.00 s until the fuel is exhausted. After that, the rocket is in free fall.
Part A
Find the maximum height ymax reached by the rocket. Ignore air resistance and assume a constant acceleration due to gravity equal to 9.80 m/s2

if weight of object on earth is 29.4 n and when we release this object is from 20m height .what is its kinetic energy at the time of collision with moon surface

a block of mass m1=1.60kg initially moving to the right with a speed of 4.00m/s on a frictionless horizontal track collides with a massless spring attached to a second block of mass m2=2.10kg initially moving to the left with a speed of 2.50m/s. the spring constant is 600N/m
at the instant m1 is moving to the right with a speed of 3.00m/s determine the magnitudeand the direction of the velocity of m2 and the compression x of the spring

A ball is thrown horizontally from the top of
a building 120 m high. The ball strikes the
ground 63 m horizontally from the point of
release. What is the speed of the ball just before it
strikes the ground?
Answer in units of m/s.

Describe the equation mx + cx + kx = 0?. And does this equation has any implications on the wave motion?.
