Answer:
East
Explanation:
In circular motion, the velocity of the object will always be tangential to the radius of the circle. In this case, since the car is at the northernmost point of the circular track, then it must be moving right or towards the east, no matter what the acceleration might be at that very moment or what the radius of the track is. If it's moving clockwise, then it moves right (towards the east).
Answer:
1.7 hours
Explanation:
Time taken in the journey = 3 hours
Distance of the entire journey = 197 miles
Distance travelled on train = x
Distance travelled on bus = 197-x
Average speed of train = 70 mph
Average speed of bus = 60 mph
Time = Distance / Speed
Distance travelled by train = 119 miles
Time taken on train = 119 / 70 = 1.7 hours
Manuel spent 1.7 hours on the train
Answer:
T = 2π√(L/g) = 2π√(0.80/9.8) = 1.79519... = 1.78 s is your closest option

Answer:
The height of the platform is 22.686 m.
Explanation:
Given;
initial velocity of Janet, u = 2.63 m/s
time of her motion, t = 1.9 s
The height of the platform is given by;
h = ut + ¹/₂gt²
substitute the given values and solve for height "h"
h = (2.63 x 1.9) + ¹/₂(9.8)(1.9)²
h = 4.997 + 17.689
h = 22.686 m
Therefore, the height of the platform is 22.686 m.
