Answer:
4. hours to travel 350km going at a rate of 80km/hr.
Explanation:
Well first you must divide 350/80=4.375~4.
Answer:
0.2m
Explanation:
F = 6 x 10^3N
k = 3 x 10^4 Nm-1
x = ?
from Hooke's law, F = kx
x = F/k = 6 x 10^3 ÷ 3 x 10^4 = 0.2m
Answer :
The frictional force on the block from the floor and the block's acceleration are 10.45 N and 0.73 m/s².
Explanation :
Given that,
Mass of block = 3.50
Angle = 30°
Force = 15.0 N
Coefficient of kinetic friction = 0.250
We need to calculate the frictional force
Using formula of frictional force
(II). We need to calculate the block's acceleration
Using newton's second law of motion
Hence, The frictional force on the block from the floor and the block's acceleration are 10.45 N and 0.73 m/s².
