Answer:
maximum acceleration will be
Explanation:
We have given that mass of the box m = 29 kg
Coefficient of static friction
Acceleration due to gravity
For maximum acceleration
So acceleration will be
So maximum acceleration will be
Answer:
v₁ = 1 [m/s].
Explanation:
This problem can be solved by using the principle of conservation of linear momentum. Where momentum is conserved before and after catching the snowball.
where:
P = linear momentum [kg*m/s]
m = mass [kg]
v = velocity [m/s]
As the momentum is conserved, it will be the same as that received by the person who catches the snowball.
That is, the person who catches the snowball moves backwards with a speed of 1 [m/s].
It means that 19.3g of gold is packed into 1cm^3.
The most common formula for average speed is distance traveled divided by time taken. The other formula, if you have the initial and final speed, add the two together, and divide by 2.
S= d/t
