Question

What is the velocity of the car, in meters per second, just after it hits a 135-kg deer initially running at 10.5 m/s in the same direction? Assume the deer remains on the car.

Answer 1

V = 27.46 m/s

Step-by-step explanation:

given,

mass of the deer(m) = 135 Kg

speed of the deer (u) = 10.5 m/s

assuming,

mass of the car(M) = 900 Kg

initial velocity of car (v) = 30 m/s

using conservation of momentum

m u + M v = (M + m )V

V is the velocity of the car as deer is on the car

135 x 10.5 + 900 x 30 = (900 + 135 ) V

28417.5 = 1035 V

V = 27.46 m/s

so, the velocity of car is equal to V = 27.46 m/s
