Answer:
the distance between Kerala and Karnataka is 425 km.
Explanation:
Given;
speed of the train, u = 85 km/h
time taken for the train to travel from Kerala to Karnataka, t = 5 hours
The distance between Kerala and Karnataka is calculated as;
Distance = speed x time
Distance = 85 km/h x 5 h
Distance = 425 km
Therefore, the distance between Kerala and Karnataka is 425 km.
Answer:
28,699m
Explanation:
The force to make the box move should be <u>μs.N=μs.m.g=m.</u><u>|</u><u>a</u><u>|</u>
then,
|a|=μs.g
Being
μs coefficient of static friction,
N the force made by the truck on the box caused by the gravity force,
m the mass,
g the acceleration of gravity
and a the acceleration of the truck.

as the truck is stopping, the acceleration is negative. then,





28,699m
26.54 m/s is the magnitude of its velocity just before it strikes the ground
h=100m,v=20m/s,g=9.8m/s
time it takes to reach the ground,
![[t=\sqrt2h/g],[=\sqrt2*100/9.8=4.51s]](https://tex.z-dn.net/?f=%5Bt%3D%5Csqrt2h%2Fg%5D%2C%5B%3D%5Csqrt2%2A100%2F9.8%3D4.51s%5D)
x= 120m
t= 4.52
v= x/t
v= 120/4.52
v= 26.54 m/s
The "speed at which an object changes its location" can be expressed using a vector number called velocity. Consider a person who moves swiftly while taking two steps forward and two steps back while remaining in one location. Velocity is a vector quantity. Therefore, velocity is cognizant of direction. The direction must be taken into account when determining an object's velocity. A speed of 55 mph is not enough information. The direction must be used to appropriately depict the item's velocity. Simply said, the direction of the velocity vector indicates the direction of motion of an object.
