Explanation:
The momentum is defined as the product between the mass and velocity:
p = m·v
Let's calculate his total momentum:
ptot = 70kg · 10m/s = 700 kg·m/s
Now we know that he's traveling 30 degrees south-east.
The momentum along the y axis will be:
py = p·cos30° = 606 kg·m/s
Along the x-axis:
px = psin30° = 350 kg·m/s

Explanation:
In the given question, there are two conditions.
Ram traveled 50 m in 30 seconds in a straight road.
Hari covers the same distance in the road; that means 50 m in 45 seconds
The formula for work w=\frac{d}{t}w=td
Ram's work w=\frac{50}{30}=1.66666w=3050=1.66666
Hari's work w=\frac{50}{45}=1.111w=4550=1.111
Ram is slower than Hari and the velocity of Ram is slower than Hari.
Ram has done less work than Hari.
Hence, Hari has done more work and he has more power than Ram.

Answer:
energia cinética
Explanation:
Passo um:
Dados fornecidos
Um bloco de peso igual a 10 N,
Constante de mola k = 50N / m
Passo dois:
A forma de energia formada é a energia cinética
Passo dois:
Da lei de Hooke, F = ke
e = F / k
e = 10/50
e = 0,2m
podemos resolver a energia cinética aplicando a fórmula
KE = 1 / 2ke ^ 2
KE = 0,5 * 50 * (0,2) ^ 2
KE = 0,5 * 50 * 0,04
KE = 1J
