Answer:
Speed, v = 45.84 m/s
Explanation:
Given that,
Radius of the curve, r = 100 m
Banking of the curve,
On the banking of curve, the speed of the vehicle is given by :
v = 45.84 m/s
So, the speed at which a 100 m radius curve banked is 45.84 m/s. Hence, this is the required solution.
Answer
given,
before collision
mass of car A = m_a = 1300 kg
velocity of car A = v_a = 35 mph
mass of car B = m_b= 1000 kg
velocity of car B = v_b = 25 mph
after collision
V_a = 30 mph
V_b = 31.5 mph
Initial momentum
final momentum
here initial momentum is equal to the final momentum of the car.
hence, momentum is conserved in the collision.
