Answer:
(a)7.48331 Km
(b) Directly above the tomb
(c) 12.53 degrees
Explanation:
Given that the distance is 3.5 Km, converted to meters we obtain 3500 m
Using the formula
where s is the distance and t is time, taking acceleration due to gravity as 9.8 then
t = 26.72 sec
We know that speed=distance/time hence to get the distance in part (a)
Distance=Speed*time
280 *26.72 = 7483.31 m converted to Km we obtain 7.48331 Km
(b)directly above the bomb
(c)
A model train traveling at a constant speed around a circular track has a constant velocity. FALSE.
Hope this helps you!
Answer:
The y-component of the normal force is 45.74 N.
Explanation:
Given that,
Mass of the crate, m = 5 kg
Angle with hill,
We need to find the y component of the normal force. We know that the y component of the normal force is given by :
So, the y-component of the normal force is 45.74 N. Hence, this is the required solution.
