A toy radio-controlled car races around a circular track in a time of 2 MINUTES, with a speed of 5.25 m/s. What is the radius of the
circular track? (will give brainliest)
Answer:
The radius will be "100.31 m". A further solving is given below.
Explanation:
The given values are:
Time,
T = 2 minutes
i.e.,
= 120 seconds
Speed,
V = 5.25 m/s
As we know
⇒ [tex]T=\frac{2 \pi R}{V}[/tex]
then,
⇒ [tex]R=\frac{TV}{2 \pi}[/tex]
On substituting the given values, we get
⇒ [tex]=\frac{120\times 5.25}{2\times 3.14}[/tex]
⇒ [tex]=\frac{630}{6.28}[/tex]
⇒ [tex]=100.31 \ m[/tex]

What is the momentum of a 200 kg truck travelling at 20 m/s?
Answer:
p = 4000 kg-m/s
Explanation:
Given that,
The mass of a truck, m = 200 kg
Speed of the truck, v = 20 m/s
We need to find the momentum of the truck. The formula for momentum is given by :
p = mv
so,
[tex]p=200\times 20\\\\p=4000\ kg-m/s[/tex]
So, the momentum of the truck is equal to 4000 kg-m/s.
