Answer: 3) 772.5 kg
Step-by-step explanation: That's what I got and I'm 100% sure that's the answer
N=6*d
0.05*n + 0.10*d = 5.20
0.3d+0.1d =5.20
d = 5.20/0.4 = 13
13 dimes and 78 nickels
The time in seconds that it took the ball to travel would be = 0.25 seconds.
<h3>Calculation of speed time</h3>
Speed can be defined as the distance covered by an object per unit time.
The speed used to kick the soccer off the ground = 56 feet per second.
The height equation= −16t² + 56t
The time= ?
The formula for speed = distance/time
56= −16t² + 56t/t
56t = −16t² + 56t/t
−16t² = -56t + 56t
−16t² = 0
Make t the subject formula,
t = √1/16
t = 0.25 seconds.
