Answer:
v = 4.264 m/s
Explanation:
It is given that,
Mass of the ball, m = 0.15 kg
Spring constant of the spring, k = 150 N/m
The spring is compressed by a distance, x = 0.05 m
The pellet's initial velocity is at an angle θ (θ < 90) above the horizontal.
Let v is the final speed of the projectile when it is at a distance h = 0.800 m below its initial height. It can be calculated using the conservation of energy as :



v = 4.264 m/s
So, the final speed of the projectile is 4.264 m/s. Hence, this is the required solution.
5! 5! 5! 5! it's 5!!!!!!!!!! Well that's what my friend told me so
Answer:
Row A is correct
Explanation:
both conduction and convection require mass to complete any heat transfer. A vacuum contains no mass
Answer:
Explanation:
We shall represent each move of coach in vector form , considering unit vector i towards east and unit vector j towards north .
he drove 100 m North
First displacement D₁ = 100 j
200 m East to reach the 133
second displacement D₂ = 200 i
500 m North to reach Papa John's
third displacement
D₃ = 500 j
Total displacement ( resultant displacement )
= D₁ + D₂ + D₃
= 100 j + 200 i + 500 j
= 200 i + 600 j
magnitude of resultant displacement
= √ ( 200² + 600² )
= √ 40000 + 360000
= 632.45 m
