It might be 144.2 m but i’m not for sure:)
Answer:
uniformly accelerated motion
Explanation:
The motion of the body where the acceleration is constant is known as uniformly accelerated motion. The value of the acceleration does not change with the function of time.
Answer:
Water droplets acts as tiny prism in the sky. The sunlight when enters these tiny droplets undergo internal reflection and also refract these rays which are dispersed causing a band of seven colors called rainbow.
Explanation:
Answer: d
Explanation:
mass of truck mt, kinetic energy of truck Ekt(Kt), Vt -speed of truck
mass of car ma, kinetic enregy of car Ekc(Kc), Vc-speed of car
mass of truck mt=2*mc
speed of truck Vt=2*Vc
Compare Kinetic energy of truck with kinetic energy of car using equation to calculatation ;
Kinetic energy of car:
Kc=(mc*Vc²)/2
Kinetic energy for truck:
Kt=(mt*Vt²)/2
Kt=((2*mc*(2*Vc)²)/2
Kt=(2*mc*4*Vc²)/2
Kt=8*mc*Vc²/2
Compare Kinteic energy truck with Kinetic energy of car:
Kt/Kc
Kt/Kc=((8*mc*Vc²)/2)/((mc*Vc²)/2)
Kt/Kc=8
