Pick up truck, if it's got a large mass. kinetic energy is 1/2 mv^2. so in terms of v the truck and cycle would be neck and neck. but truck is presumably more massive.
Answer:
Speed does the 60-kg skater acquire relative to the ice = 0.281 m/s
Explanation:
Momentum is conserved in this case.
Initial momentum = Final momentum.
Initial momentum = Initial momentum of skater 1 + Initial momentum of skater 2
Initial momentum = 45 x 0 + 60 x 0 = 0 kg m/s
Final momentum = 45 x 0.375 + 60 x u = 16.875 + 60 u
Here we need to find u.
We have
0 = 16.875 + 60 u
u = -0.281 m/s
Speed does the 60-kg skater acquire relative to the ice = 0.281 m/s
Answer:
The potential energy change is 0.596 J.
Explanation:
Given that,
Potential difference =14.9 V
Charge q =0.0400 C
We need to calculate the change potential energy
The potential energy change is the product of the charge and potential difference.
Using formula of change potential energy
Hence, The potential energy change is 0.596 J.
Complete Question
A student bikes to school by traveling first dN = 0.900 miles north, then dW = 0.300 miles west, and finally dS = 0.100 miles south.
Similarly, let d⃗ W be the displacement vector corresponding to the second leg of the student's trip. Express d⃗ W in component form.
Express your answer as two numbers separated by a comma. Be careful with your signs.
Answer:
The value is
Explanation:
From the question we are told that
The first displacement is i.e positive y-axis
The second displacement is i.e negative x-axis
The final displacement is i.e negative y-axis
Generally dW in component for is
Generally the total displacement of the student is mathematically represented as
