Question

In Sacramento a 4000kg SUV is traveling 30m/s south on Truxel crashes into an empty school bus, 7000kgtraveling east on San Juan. The collision is perfectly inelastic

Answer 1

Answer:

1.71m/s

Explanation:

mass of SUV = 4000kg

velocity of SUV = 30m/s

mass of school bus = 7000kg

speed of school bus = x

both the vehicles come to rest after collision.

SUV = school bus

4000 × 30 = 7000 × x

7000x = 12000 ( transposing )

x = 12000

7000

x = 1.71m/s
