Pebble in a sling shot!! And I believe the boulder falling !
Answer:
944.12 J
Explanation:
To solve for the energy change we use the equation Q=mc(Delta)t
Let's identify the variables we have:
m (mass) = 49.2 g
c (specific heat) = .4494
delta t (change in temp.) = final - initial = 58.9-16.2 = 42.7 degrees Celsius
Q= (49.2)(.4494)(42.7)
= 944.12 J

Answer:
Distance = 72 meters.
Explanation:
Given data:
speed of burrito = 4 meter/ second
Time taken in flight = 18 seconds.
Required: The distance covered during this time and having the above speed by the burrito.
Solution :
Formula of speed is given below.
Speed = distance / time interval
By putting the values of speed and time, we get,
4 meter / second = distance / 18 seconds.
Multiply 18 both, we get
4 x 18 = distance
Distance = 72 meters.
