A 454 kg CAR approaches a stop light moving 20 m/s, but the driver is texting and does not slow down! The CAR collides with a TRUCK (908 kg) at rest at the stop light. After the collision the CAR is traveling at 5 m/s and the TRUCK is traveling at 7.5 m/s in the same direction. What is the total (sum) momentum of the CAR & TRUCK Before the collision? and After? Can somebody pleeease walk me through this? With equations and your thought process and stuff. Thank you *will give brainliest*

b. labeled and listed

explanation:

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
