A home run is hit in such a way that the baseball just clears a wall 10 m high, located 126 m from home plate. The ball is hit at an angle of 33° to the horizontal, and air resistance is negligible. (Assume that the ball is hit at a height of 1.0 m above the ground.)
Find the initial speed of the ball.
m/s
Find the time it takes the ball to reach the wall.
s
Find the velocity components of the ball when it reaches the wall.
x-component m/s
y-component m/s
Find the speed of the ball when it reaches the wall.
A pulsar is an extremely dense neutron star which is a highly magnetized. As it rotates it emits a beam of electromagnetic radiation which can sweep across the earth at very regular intervals. by what amount would the pulsar radius have had to shri..
A 1 115.0 kg car traveling initially with a speed of 25.000 m/s in an easterly direction crashes into the back of a 8 200.0 kg truck moving in the same direction at 20.000 m/s. What is the velocity of the truck right after the collision
A 795 kg car moving at 26 m/s brakes to a stop. The brakes contain about 15 kg of iron, that absorbs the energy. What is the increase in temperature of the brakes.
