A 750 kg car is moving at 20.0 m/s at a height of 5.0 m above the bottom of a hill when it runs out of gas. From there, the car
S_A_V [24]

Answer:

Explanation:

Kinetic energy at the height = 1/2 m v²

= 1/2 x 750 x 20²

= 150000 J

Its potential energy = mgh

= 750 x 9.8 x 5

=36750 J

Total energy = 186750 J

Its total kinetic energy will be equal to 186750 J , according to conservation of mechanical energy

If v be its velocity at the bottom

1/2 m v² = 186750

v = √498

= 22.31 m /s

A 900-kg car traveling east at 15.0 m/s collides with a 750-kg car traveling west at 20.0 m/s. The cars stick together. What is
andriy [413]

Answer:

17.27m/s

Explanation:

M1U1 + M2U2 = (M1+M2)V

(900x15) + (750 x 20) = (900+750)V

13500+15000 = (1650)V

28500 = 1650v

V = 28500/1650 = 17.27m/s

V = 17.27m/s
