Answer: Normal force, N = 141.64 Newton
Explanation:
All the forces acting on the system and described in free body diagram are:
1) gravitational pull in downward direction
2) Normal force in upward direction
3) External force of 40 N acting at an angle of 37° with the horizontal can be resolved in two rectangular components:
i) F Cos 37° along the horizontal plane in forward direction and
ii) F Sin 37° along the vertical plane in downward direction
Applying the Newton's second law, net forces in the vertical plane are:
Net force, f = N - (mg + F Sin 37°)
As there is no acceleration in the vertical plane hence, net force f = 0.
So,
N - (mg + F Sin 37°) = 0
Adding (mg + F Sin 37°) both the sides in above equation, we get
N = mg + F Sin 37°
N = 12 9.8 + 40 0.601 because (Sin 37° = 0.601)
N = 117.6 + 24.04
N = 141.64 Newton
Answer:
1.5 minutes
Explanation:
The time it takes for you to drive a distance of 53km at 88.8 km/h is
t = s/v = 53 / 88.8 = 0.5968 hours
Similarly the time it takes for your friend to drive a distance of 53km at 92.6 km/h is
53 / 92.6 = 0.572 hours
Obviously since it takes less time for your friend, he will arrive first if both of you start at the same time. His waiting time would be
0.5968 - 0.572 = 0.0245 hours or 0.0245 * 60 = 1.5 minutes
