Answer:
Relation between kinetic energy of truck and kinetic energy of car is given as
Explanation:
As we know that mass of truck is four times the mass of car
and the speed of truck is double that of speed of car
now we have kinetic energy of the truck is given as
similarly kinetic energy of car is given as
now from above two equations we have
so we have
The correct options are: B, C and D.
In fact:
- B is true, because the motion of the projectile can be decomposed in two independent motions on the x and y axis. On the x-axis, there is no acceleration; while on the y-axis, the projectile is accelerating towards the ground with
(acceleration of gravity)
- C is true, because the two motions on the horizontal and vertical direction are independent. In particular, the horizontal motion is a uniform motion (constant velocity), while the vertical motion is a uniformly accelerated motion (because of the gravitational acceleration g acting on the projectile)
- D is true, in fact (if we neglect air resistance) gravity is the only force acting on the projectile.
