Solve the all parts of given problem:
Problem: A frictionless toy car is placed on a ramp, which is inclined at an unknown angle ? with respect to the horizontal. Starting from rest, the car is allowed to roll freely down the ramp. After a time interval of 0.91 s, the car has traveled a distance of 1.1 m down the ramp and is moving with speed Vf.
Part A: Find the speed of the car at the end of the 0.91-s time interval.
Vf=_____m/s
Part B: What is the angle of inclination of the ramp, in degrees? Assume that g = 9.81 m/s2.
Please show all work how you obtained the angle of inclination of the ramp.
