He should choose the room that’s 15 F.
-5 C = 23 F
Meaning that 15 F is below -5 C and 25 F is not.
the answer you are looking for is the crust!
have a great day :D
Answer:
The motorcycle travelled 69.73 m during these 3.1 s.
Explanation:
In order to calculate the distance that the motorcycle travelled we first need to obtain the acceleration rate that was used to brake the vehicle. We do that by using the following formula:
a = (V_final - V_initial)/(t) = (15 - 30)/(3.1) = -4.84 m/s^2
The distance is given by the following formula:
S = (V_final^2 - V_initial^2)/(2*a)
S = (15^2 - 30^2)/[2*(-4.84)] = (225 - 900)/(-9.68) = -675/(-9.68) = 69.73 m
The motorcycle travelled 69.73 m during these 3.1 s.
Answer:1.89 m
Explanation:
Given
Block travels in first second
It is released from rest i.e. initial speed is zero (u=0)
using
where a=acceleration
here acceleration is the component of gravity on incline plane (say )
so
So distance traveled in
So distance traveled in is
