Two figure skaters are coasting in the same direction, with the leading skater moving at 5.5 m/s and the trailing skating moving at 6.2 m/s. When the trailing skater catches up with the leading skater, he picks her up without applying any horizontal forces on his skates. If the trailing skater is 50 heavier than the 50-kg leading skater, what is their speed after he picks her up?
A ball of mass m = 1.80 kg is released from rest at a height h = 65.0 cm above a light vertical spring of force constant k as in Figure P5.64a. The ball strikes the top of the spring and compresses it a distance d = 9.00 cm as in Figure P5.64b. Neglecting any energy losses during the collision, find (a) the speed of the hall just as it touches the spring and (b) the force constant of the spring.
The only force acting on a 2.0-kg body moving along the x axis is given by Fx = 2x where force is measured in Newtons, N, and x is in meters. If the velocity of the object at x = 0 is +3.0 m/s, how fast is it moving at x = 2.0 m?
How long does it take a 2500 kg car to slow down from 15 m/s if it strikes a wall with a force of 10000 N? Assume the collision with the wall is elastic.
A ball of mass 160 g is dropped from a height 1.5 m and bounces off the floor with a velocity 3.0 m/s [Up]. If the average Force on the ball from the floor is 15 N [up], for how long is the ball in contact with the floor in milliseconds?
Calculate the final speed (in m/s) of a 104 kg rugby player who is initially running at 7.75 m/s but collides head-on with a padded goalpost and experiences a backward force of 1.65 ✕ 104 N for 6.00 ✕ 10−2 s.
A ball having mass 3.2kg and velocity 9.4m/s travels due east. An impulsive force at point O, makes it change direction to due north with velocity 9.9 m/s. What is the angle counterclockwise from the +x (east) axis of the impulsive force in degrees?
Hello, can you please help me with this physics question? A ball with a mass of 0.17 kg is bounced off a tenis court. Before hiting the ground, the ball is moving at a velocity of (1.4, -8.5)m/s. If the ground exerts a force of 203 N acting upward for a time of 0.0125s, what is the final velocity of the ball leaving the ground of the tenis court? (the y value is positive in the upward direction)
A 0.203 kg baseball is pitched to a batter with an initial speed of 18.4 m/s, if the bat delivers a force of 2.09E3 N for a time of 0.00300 s, what speed does the baseball have as it is hit back towards the pitcher?
When a 1984 Alfa Romeo Spider sports car accelerates at the maximum possible rate, its motion during the first 20 s is extremely well modeled by the simple equation: v2x =(2P/m)*twhere P=3.6×104 W is the car's power output, m = 1200kg is its mass, and vx is in m/s. That is, the square of the car's velocity increases linearly with time Find a symbolic expression, in terms of P, m, and t, for the car's acceleration at time t.
During the pitching motion, a baseball pitcher exerted an average horizontal force of 60 N against the 0.15 kg baseball while moving it through a horizontal displacement of 2.0 m before he released it. If the baseball’s velocity at the start of the pitching motion was zero, how fast was the ball moving at the instant of release?
A 0.544-kg ball, initially moving with a speed of 2.54 m/s, bounces off a wall and then moves with a speed magnitude half of its original directed in the opposite direction. If the ball is in contact with the wall for 5.7 ms, what is the magnitude of the average force that the wall exerts on the ball? Express your answer in two decimal places, in Newtons.
