Answer:
correct answers will be
2. The train is not an inertial frame of reference.
5.The train may be moving at a constant speed in a circle.
8. The train must be accelerating.
Explanation:
As we know that string makes an angle with the horizontal
so we can write the force equation for the given ball
also in Y direction
now we have
now we can conclude that train is accelerating with acceleration same as gravity
now correct answers will be
2. The train is not an inertial frame of reference.
5.The train may be moving at a constant speed in a circle.
8. The train must be accelerating.
Answer:
his displacement is 772.85 ft
Explanation:
Given;
initial velocity of his jump, u = 2 ft/s
final velocity of his jump, v = - 223 ft/s
time of motion, t = 7 seconds
acceleration due to gravity, g = 32.17 ft/s²
Let downward motion = positive direction
Let his displacement after 7s = Δh
Apply the following kinematic equation to determine his displacement.
Therefore, his displacement is 772.85 ft
