A car with a mass of 1750 kilograms, traveling at a speed of 15 meters/second, crashes into a wall and stops. What is the kinetic energy after this perfectly inelastic collision? a
2.0 × 105 joules

b
1.0 × 104 joules

c
2.6 × 104 joules

d
0.0 joules

Isuck at math i am no sorry

10 is the . . .

Initial velocity,  u = 4.9 m/sfinal velocity = v m/sinitial height,  h₁ =  245 m    final height, h₂ = 0a = -9.8  m/s²time taken = t secondss = ut + 0.5at²⇒  (h₂-h₁) = ut + 0.5at²⇒  0-245 = 4.9t + 0.5×(-9.8)×t²⇒ -245 = 4.9t - 4.9t²⇒ 4.9t² -4.9t -245 =0solving it, we get   t = 7.59sv  = u +  at = 4.9 -9.8×7.59 = 4.9 - 74.38 = -69.48 m/svelocity is  69.48 m/s downward

He sandals were out in the sun so the got hotter. which is why her feet felt hot.
