Question

A physics student monitors the speed and kinetic energy of a 0.37-kg traveling object. At a time of t = 1.0 s, the object is traveling with a speed of 6.5 m/s and at a time of t = 4.0 s, the object has a kinetic energy of 30 J. Determine the following. kinetic energy of the object at t = 1.0 s=__?__J

Answer 1

The kinetic energy of the object at t = 1.0 s is 7.53625 J.

Step-by-step explanation:

The kinetic energy of an object can be calculated using the formula KE = 1/2 mv^2, where m is the mass of the object and v is its velocity. At t = 1.0 s, the object is traveling with a speed of 6.5 m/s. Given the mass of the object is 0.37 kg, we can calculate its kinetic energy at t = 1.0 s as follows:

KE = (1/2) (0.37 kg) (6.5 m/s)^2 = 7.53625 J.
