What is the mass-energy equivalent of a 0.15 kg baseball?
A baseball of mass 0.15 kg is thrown at a batter at a speed of 42 m/s, and, after being hit, travels in the opposite direction. If the final speed of the baseball is 35 m/s and the baseball and the bat are in contact for 2 ms, what is the average force the bat applies to the baseball? What percentage of the original kinetic energy is lost?
A baseball has a mass of 0.15 kg and radius 3.7 cm. In a baseball game, a pitcher throws the ball with a substantial spin so that it moves with an angular speed of 31 rad/s and a linear speed of 55 m/s. Assuming the baseball to be a uniform solid sphere, determine the rotational and translational kinetic energies of the ball in joules. KErotational = KEtranslational=
A baseball has a mass of 0.15 kg and radius 3.7 cm. In a baseball game, a pitcher throws the ball with a substantial spin so that it moves with an angular speed of 30 rad/s and a linear speed of 39 m/s. Assuming the baseball to be a uniform solid sphere, determine the rotational and translational kinetic energies of the ball in joules. KE rotational = .012034 x What is the moment of inertia of a solid sphere?) KEtranslational...
Find the de Broglie wavelength of a baseball of mass 0.15 kg moving at a speed of 12.8 m/s (29 mi/hr).
B) A baseball of mass 0.15 kg thrown at 100 mph has a momentum of 6.7 kg x m/s. if the uncertainty in measuring this momentum is 1.0 x 10-7 of the momentum, calculate the uncertainty in the baseballs position.
A fielder tosses a 0.15 kg baseball at 36 m/s at a 27 ∘ angle to the horizontal. Part A: What is the ball's kinetic energy at the start of its motion? Part B: What is the kinetic energy at the highest point of its arc?
A fielder tosses a 0.15 kg baseball at 26 m/s at a 33 angle to the horizontal. Q1) What is the ball's kinetic energy at the start of its motion? Q2) What is the kinetic energy at the highest point of its arc?
S2. (5 pts) A baseball pitcher of mass 80 kg at rest pitches a baseball of mass 0.15 kg at 50 m s-1 towards home plate. Throwing that ball, the pitcher recoils in the directly opposite direction which is towards second base. What is the speed at which the pitcher is pushed towards second base?
A 0.15 kg baseball travelling horizontally is hit by a baseball bat. The velocity of the baseball changes from +2-m/s to -20m/s as a result of the contact. a) what is the magnitude of the impulse delivered to the ball? b) If the ball is in contact with the bat for 1.20msec, what is the average force delivered by the bat? c)If the instantaneous force delivered by the bat increases linearly for 0.65 ms and then decreases linearly for 0.65ms,...
Consider a baseball (m = 0.15 kg) confined to a one-dimensional box that is 30 cm wide. If we treat the baseball as a wave, What is the momentum of the baseball in the second exited state?
