Answer:
Since Force is a vector quantity, It depends on both magnitude and direction.
So, the resultant depends also on the direction.
Answer:
The time period of the rope waves is seconds
Explanation:
The period of a wave, T is equal to 1 divided by the frequency of the wave
The number of waves produced per second by the wave = 7 waves
Therefore;
The frequency of the wave, f = 7 complete cycles per second = 7 Hz
f = 7 Hz
The time period of the rope waves, T = seconds
It’s easier to lift the wheelbarrow when the load is near the front because there isn’t any pressure near the back where the handles are.
Impulse = change of momentum
Impulse = 45 x 6 = 270 Ns
The combined mass of Danny+skateboard is 72.5 kg
Explanation:
We can solve the problem by using Newton's second law of motion:
where:
F is the net force applied on Danny and the skateboard
m is the mass of Danny+skateboard
a is the acceleration
Here we have the following data:
F = 29 N is the force applied
is the acceleration of Danny and the skateboard
Solving for m, we find their combined mass:
