Question

Answer this question of physics pls.

Answer 1

Answer:

0

Explanation:

new velocity will be 0 m/s

since the vehicle sticks to the hoarding after the collision.

Answer 2

Mass of vehicle($M_{ A}$): 3000kg

Initial velocity of vehicle($U_{A}$): 2.5m/s

Final velocity of vehicle= Final velocity of hoarding (collision)

Let final velocity be V

Mass of Hoarding($M_{B}$)=200kg

Initial velocity of hoarding ($U_{B}$)=0m/s

$M_{A} U_{A} + M_{B} U_{B} = M_{A} V+M_{B} V$

3000kg x 2.5m/s + 200kg x 0m/s =  3000kg x V + 200kg x V

7500kg m/s+ 0kg m/s = V(3000kg+200kg)m/s

7500kg m/s = V(3200kg)m/s

$\frac{7500kg m/s}{3200kg}$ =Vm/s

2.34m/s
