The kinetic energy of particle continuously increase with time
a. The resultant force on the particle must parallel to velocity at all instants
b. The resultant force on the particle at an angle less than all the time
c. Its height above the ground level continuously decrease
d. The magnitude of its linear momentum is increasing continuously
a. The resultant force on the particle must parallel to velocity at all instants
b. The resultant force on the particle at an angle less than all the time
c. Its height above the ground level continuously decrease
d. The magnitude of its linear momentum is increasing continuously
View answer and explanation
Correct option: D
b, d are correct
Option D (b, d are correct) is correct because if kinetic energy increases continuously, the resultant force must have a component along the velocity (angle less than 90 degrees), and the magnitude of linear momentum also increases continuously.
