Answer:
she should beat a speed of v₂ = 6.04 m/s in order to win the competition
Step-by-step explanation:
Since the momentum p is defined as
p = m*v
where
m= mass of the ball
v= velocity of the ball
denoting 1 and 2 as the first and second bowler , then to reach the momentum of the first bowler
p₂=p₁
therefore
m₁*v₁ = m₂*v₂
v₂ = v₁ * (m₁/m₂)
replacing values
v₂ = v₁ * (m₁/m₂) =8.6 m/s * (4.5 kg/6.4 kg ball) = 6.04 m/s
then since the momentum p = m*v increases with increasing v (at constant m) , she should beat a speed of v₂ = 6.04 m/s in order to win the competition
Answer:
m= 11.4
Step-by-step explanation:
13.5= m+2.1
Subtract 2.1 to both sides
13.5= m+2.1
-2.1 -2.1
11.4= m
Answer:
The answer is less than 90 degrees
Step-by-step explanation:
It would be: 360- (101+133+76)
360-310 = 50 degree
Answer:
m+2e=330
3m+1e=515
use simultaneous formula to get
m=37
e=146.5
