the direction of the impulse on a struck baseball

! With what velocity must a 0.53-kg softball be moving to equal the momentum of a 0.31-kg baseball moving at 21 m/s? The batter hits the ball with an impulse of 10 N s so that it reverses its motion. Its velocity changes from +20 m/s to -20 m/s. Find the direction of the impulse delivered to the ball by the bat. 2. Sixty Baseball Physics Problems © page 1 !! The Physics of Baseball. Explain.
An estimated force vs. time curve for a baseball struck by a bat is shown in Figure P6.8. asked by Mileena on March 15, 2017; Physics. 2 4 avg 3 1.0 10 kg m s 1.3 10 N 8.0 10 s p F t 4.2 The Principle of Conservation of Linear Momentum The impulse – momentum theorem leads to the principle of conservation of linear momentum, when the sum of average external force acting on the system is zero. Its velocity changes from +20 m/s to -20 m/s. CHAPTER 4 IMPULSE AND MOMENTUM 4.1 The Impulse – Momentum Theorem To describe the concept of impulse, let’s refer to the situation below: What happen when a baseball bat strikes a ball? This estimate assumes that during the collision, the collision force is very large compared to all other forces on the object. The magnitude of force is applied to the ball by the bat, where the force rises to a maximum value at the point of impact and then returns to zero when the ball leaves the bat. Sixty Baseball Physics Problems © page 1 !! You are at the front of a floating canoe, close to the shore.

Physics 140 HOMEWORK Chapter 09A Q4. Calculate (or estimate) the impulse I and the time Δt. This force is required to change a 5 1/8th-ounce ball from a speed of 90 mph to a speed of 110 mph, this distorts the baseball to half its original diameter and the bat is compressed one fiftieth of it's size." We also know that acceleration is equal to the change in velocity, divided by the time interval. Assume that the ball and bat are in contact for 1.5 ms Find the magnitude of the impulse delivered to the ball by the bat. The batted ball has a velocity of 30m/s towards the pitcher. ——— all are equal. Newton's second law states that average net force equals mass times acceleration. Ch7 Page 4 asked by Alex on March 25, 2013; Physics. The free-body diagrams in Fig. The impulse is the area under the curve, which is J = 12F 0 t 0 in each case. The product of force and time is a quantity called impulse (measured in newton seconds). ! ejected at a high speed, the impulse it feels is large and forward, and the water then provides a large impulse back on the hose, which makes it hard to hold. Instead you land in the water. After striking the bat, the ball moves vertically upward with a velocity Vf= (21m/s )ybar.
Can someone please help me with the following 2 questions?

"The batter exerts some 6000-8000 pounds of force on the ball. Just before, the ball has velocity of magnitude 11.4 m/s and angle = 31.4 degrees.
