Question

if a bike is moving with 60 m/s and momentum is 7920 kg km per hour...find mass ?​

Answer 1

Answer:

36.67 kg

Step-by-step explanation:

If a body of mass m be moving with velocity v

Then, the momentum = mv

Now, we have that

7920 kgkm/h = m× 60m/s

$or \: \frac{7920 \times 1000}{60 \times 60} kgm \: per \: sec \: = 60m \: \frac{m}{sec}$

or, m =

$\frac{7920 \times 1000}{60 \times 60 \times 60} kg$

$= \frac{7920}{6 \times 6 \times 6} kg$

= 36.67 kg. Ans
