True a matter of fact with an incredible amount of it
Answer:
a) 12.01 W
b) 63.506 N
c) 11.82 s
Explanation:
Given data:
mass = 75 kg
slope of inclination = 3 degree
speed of skier is 2.00 m/s
air Resistance = 25 N
a) From the given information we have following relation
Power output
b) average force can be calculate as
F_n = 63.506 s
c)
force of acceleration is f = ma
solving for acceleration
a = 0.846 m/s^2
we know acceleration is given as
solving for time t
t = 11.82 s
Answer:
1 m/s² down
Explanation:
"Calculate the acceleration of the elevator, and find the direction of acceleration."
Sum of forces in the +y direction:
∑F = ma
N − mg = ma
0.9 mg − mg = ma
-0.1 mg = ma
a = -0.1 g
a = -1 m/s²
