Light because it is an electromagnetic wave and they can travel through the vacuum in outer space.
Answer:
Below
Explanation:
To find the acceleration of the car, we can use this formula :
acceleration = net force / mass
acceleration = 2070 N / 1350 kg
acceleration = 1.53333 m/s^2
acceleration = 1.53 m/s^2
Hope this helps!
Answer:
75 Newtons.
Explanation:
From Newton's second law of motion,
F = m(v-u)/t................... Equation 1
Where F = force exerted by the ball on the bat, m = mass of the ball, v = final velocity of the ball, u = initial velocity of the ball, t = time
Given: m = 0.6 kilogram, u = 0 meter per seconds (at rest), v = 25 meters per seconds, t = 0.2 seconds.
Substitute into equation 1
F = 0.6(25-0)/0.2
F = 3(25)
F = 75 Newton.
Hence the magnitude of the average force exerted by the ball on the bat = 75 Newtons.
