1) A 1.9-kilogram mud ball drops from rest at a height of 18 m. If the impact between the ball and the ground lasts 0.56s, what is the average force exerted by the ball on the ground?
2) A 4.90-kg ball, moving to the right (positive direction) at a velocity of +2.30 m/s on a frictionless table, collides head-on with a stationary 7.90-kg ball. Find the final velocity of the 4.90-kg ball if the collision is elastic.
A) How fast should the car be traveling just as it leaves the cliff in order to just clear the river and land safely on the opposite side? B) What is the speed of the car just before it lands safely on the other side?
A 1.00 kg glider on a horizontal air track is pulled by a string at an angle θ. The taut string runs over a pulley and is attached to a hanging object of mass 0.500 kg .
At launch, the space shuttle's engines offer a thrust of 29 x 10^6N, and it accelerates upward at 1.75 m/s^2. What is the shuttle's mass.
A force of k is applied to an object for a small fraction of a second, t_k, less than the duration of one frame, t_f. Our simulation doesn't support applying forces for less than an entire frame, so if we wanted to simulate the effect of force k over..
Find out the moment of inertia of the wheel. Initially the wheel rotates with an angular speed , causing the block to rise with a linear speed = 0.33 .
From the shape of total energy vs. time plot, what can you conclude about the conservation of mechanical energy in your mass and spring system.
A 7.3 x10^3 kg space vehicle and its empty 6.8 x 10^2 kg booster unit are moving together through space at 370 m s. An explosion lasting 2.2s is used to separate the two parts.
A ball of mass 1.020 g and positive charge q =45.2 microC is suspended on a string of negligible mass in a uniform electric field. We view that the ball hangs at an angle of theta=15.0 from the vertical. What is the magnitude of the electric field.
Find out the force each hand exerts on the shaft when the shaft is rotating in the horizontal plane about its center at 5×10-2 {rm rev/s}.
A pipe with a 2m diameter carries water having a velocity of 4 m/s. What is the mass flow rate of the water in kg/s at the following temperatures.
Two small insulating spheres with radius 9×10-2 are separated by a large center-to-center distance of 0.52. One sphere is negatively charged.
Suppose the length of a clock's pendulum is changed by 1.000%, exactly at noon one day. What time will it read 24.00 hours later, assuming it the pendulum has kept perfect time before the change? Note that there are two answers, and perform the ca..
