X-component of a projectile in flight =
(initial x-component)
plus
(initial horizontal component of velocity) x (flight time so far)
Answer:
Potential energy is stored energy and the energy of position––gravitational energy. There are several forms of potential energy. Electrical Energy is the movement of electrical charges. Everything is made of tiny particles called atoms.
Horizontal velocity: 81.9 km/h
Vertical velocity: 57.4 km/h
Explanation:
We can solve this problem by resolving the velocity vector into its component along the horizontal and vertical direction.
The horizontal velocity of the stunt bike is given by:

where
v = 100 km/h is the magnitude of the velocity
is the angle of projection
Substituting, we find

The vertical velocity instead is given by

where


Substituting,

Answer:
It made landfall.
Explanation:
On land there is more friction than in open water, so it slowed down the hurricane.
Answer:
The kinetic energy of tennis ball is higher than that of baseball.
Explanation:
mass of baseball
= 0.14 kg
velocity of baseball
= 41 m/s
mass of tennis ball
= 0.058 kg
velocity of tennis ball
= 67 m/s
To find: the kinetic energy of baseball
and tennis ball 
We know that the kinetic energy is given by the equation,
KE = 
the kinetic energy of baseball
= 
= 
= 117.67 J
the kinetic energy of tennis ball
= 
= 
= 130.181 J
Hence
>
, the kinetic energy of tennis ball is higher than that of baseball
