1) Write down a function named as kineticEnergy() which determines the kinetic energy of an object in accordance with the following formula:
Kinetic energy = 1/2 mv2
Where m signify the object’s mass in kilograms, and v signify the object’s velocity in meters per second. Your function must take two float arguments for mass and velocity, and return answer as another float value.
A speedboat starts from rest and accelerates at +2.01 m/s2 for 6.95 s. At the end of this time, the boat continues for the additional 5.70 s with an acceleration of +0.518 m/s2. Following this, the boat accelerates at -1.49 m/s2 for 8.20 s.
A 43kg block of ice slides down the frictionless incline 1.50m long and 0.82m high. A worker pushes up against the ice, parallel to the incline, so that the block slides down at constant speed.
Use approximate calculations assuming constant current during the output pulse. Calculate the ampere-hour rating of the battery so it lasts for five years.
Compute the semi major axis of the star orbit
A 32.0 kg hammer strikes a steel spike 2.70 cm in diameter while moving with speed of 24.0 m/s. The hammer rebounds with speed 11.0 m/s after 0.110 s. What is an average strain in the spike all through the impact.
What is the tension in the string
A baseball is thrown straight up. The drag force is proportional to.In terms of, what is the y-component of ball's acceleration when its speed is half its terminal speed and it is moving up.
A 59.0 kg skateboarder wants to just make it to the upper edge of a "quarter pipe," a track that is one-quarter of the circle with a radius of 3.80 m.
A 2.0 kg ball swings in a vertical circle on the end of an 80cm long string. Calculate the speed, magnitude and direction of acceleration
Find out how fast a GPS satellite is moving relative to someone on the ground and from that how much slower time runs where it is in orbit relative to someone on the ground.
If his arms are capable of exerting a force of 1400 on the vine, what is the maximum speed he can tolerate at the lowest point of his swing? His mass is 82, and the vine is 6.00 long.
