We know that Kinetic energy = 0.5mv^2
= 0.5*65*(1500/(4*60))^2
= 1270 J answer

A runner has a certain amount of kinetic energy. The runner now triples her speed. How much kinetic energy does the runner have now?
We learned in class that the kinetic energy (KE) of an object with mass m moving at velocity v is KE =½ m v^2. Accordingly, the kinetic energy (KE) per unit mass (m) of a body moving at velocity v is KE/m=v^2 /2. What is the asteroid’s kinetic energy per unit mass (J/kg) for an impact at this velocity? State your answer in units of J/kg. velocity is 29.8 km/s
Read the description of the motion and decide if the kinetic energy (KE) and the gravitational potential energy (PE) is increasing, decreasing, or remaining constant A box of shingles is dropped from the roof and falls to the ground below. kinetic energy Increases kinetic energy decreases c. kinetic energy remains constant d. gravitational potential energy Increases e gravitational potential energy decreases f gravitational potential energy remains constant
Given the formula of the kinetic energy of a particle m
with
speed v:
KE = 1⁄2mv2 ,
and the formula of the gravitational potential energy:
PE = -GMEm/R,
where G is gravitational constant and ME and R=6378 km are the
mass and the radius of Earth. Now the particle is shot from Earth
surface to space. Find the minimum required initial speed for this
particle to completely escape the influence of Earth gravity (i.e.
PE=0). Notice that the gravitational...
