Answer:
78 miles
Explanation:
The average velocity of the bus is given by:
where
d is the displacement (the distance between the two cities)
t is the time taken
In this problem, we have
t = 1.5 h
v = 52 mph
So, we can solve the formula to find d, the distance between the cities:
I think it’s C I’m not completely sure
Answer:
Explanation:
velocity of first projectile after 3 s
v = u - gt
v = 49.4 - 9.8 x 3
= 20 m /s
Velocity of second projectile after 3 s after being dropped from rest
v = u + gt
= 0 + 9.8 x 3
= 29.4 m /s
They will be moving in opposite direction at the time of meeting , so their relative velocity
= 20 + 29.4 = 49.4 m /s
From the frame of reference of the first projectile, the velocity of the second projectile will be 49.4 m /s .
