Answer:
Force will be 7.97 N
Explanation:
We have given that earth is at s distance of 42000 km from the earth center
So r = 42000 km = 42000000 m
Mass m = 1500 kg
Angular velocity of earth 
We have to find the force
We know that force is given by

Answer:
6.96 s
Explanation:
<u>Given:</u>
- u = initial speed of the automobile = 0 m/s
- a = constant acceleration of the automobile =

- v = constant speed of the truck = 8.7 m/s
<u>Assume:</u>
- t = time instant at which the automobile overtakes the truck.
At the moment the automobile and the truck both meat each other the distance travel by both vehicles must be the same.

Since t = 0 s is the initial condition. So, they both meet again at t = 6.96 s such that the automobile overtakes the truck.
