You'll never get the correct answer without the correct conversion factor. Note carefully that you have no decimal. It should be
<span>1 km = 0.6214 miles </span>
<span>1000 m = 1 km </span>
<span>60 seconds = 1 minute </span>
<span>60 minutes = 1 hour. </span>
<span>2.998E8 m/s x (1 km/1000m) x (0.6214 miles/km) x (60 sec/min) x (60 min/hr) = ?</span>
Answer:
Velocity = 0.105m/s
Explanation:
Using conservation of momentum:
Momentum before impact= mass of ball × velocity of ball
= 0.400×10.8= 4.32
Momentum after impart= mass of ball × velocity of ball + mass of olaf × velocity of olaf
= 4.35 +3.56 + 74.9Vf
Vf=7.88_74.9 = o.0.105m/s
3.3 x10^4N/m²
6.7 x105N/m²
Explanation:
Let the young modulus of the relaxed biceps be
Y= F¹Lo/ deta L1 x A
= 25 x0.2/ 0.03* 50cm²(1m²
0.0004cm^-²)
= 3.3x10^4N/m²
But young modules of muscle under maximum tension will be
Y= F"Lo/ deta L" x A
= 500x 0.2/ 0.03* 50cm²(1m²
0.0004cm^-²)
= 6.7 x10^5N/m²
A ball is fired with speed v = 180 m/s at an angle 40 degree
So here we can say the components of velocity is given as


now when ball will reach the maximum height its velocity in vertical direction will become zero
so here we can say

now using kinematics we will have


so maximum height is

so it will reach at maximum height of 683 m
