A car traveling at 120 km/h strikes a tree. The front end of the car compresses and the driver comes to rest after traveling 0.85 m.

You are playing a game and you push a cart to give it in. speed. The cart starts at the bottom (zero) of a ramp and after reaching the top of the ramp, the cart travels across a horizontal track w/ friction. The mass of the cart is 44 x 10^-3 kg. The ramp is 56 cm high. The length is 70 cm. What can you infer of the intial speed in (m/s)

A car of mass, m 1500 kg going at an initial speed, v, = 30 m/s exits a main road onto a banked lane. The car slows down due to a gain in height and due to friction from its breaks. The final speed of the car, V 15 m/s after the car has travelled a distance, s 100 m along the road and has been raised by a height, h = 10 m. W=15 m/s 3D30 m/s h=D10 m What is the net force applied by the breaks of the car assuming that this force is constant in time? 50 kN 1.8 kN 1.3 MN 3.6 kN 34 kN N 00 A ctv MacBook Air COD F4 114 R

A 10 m long vertical cannon is used to accelerate a 1.0 kg ball straight up into air. A constant force of 13.2N is used to access bowling ball length of the canon. what is the ball's approximate velocity as it leaves the canon assuming no energy loss to friction​

A car moving at 70 km/h collides with a concrete bridge support. The bridge support is unaffected but the front of the car is compressed by 0.94m. What average force must a seatbelt exert in order to restrain a 75 kg passenger during this collision.

You are driving your car on a straight road with a coefficient of friction between the tires and the road of 0.55. A large piece of debris falls in front of your view and you immediate slam on the brakes, leaving a skid mark of 30.5 m (100-feet) long before coming to a stop. A policeman sees your car stopped on the road, looks at the skid mark, and gives you a ticket for traveling over the 13.4 m/s (30 mph) speed limit. Should you fight the speeding ticket in court?

A 80.0 kg skater with the Birmingham Bulls hockey team with an initial speed of 7.8 m/s stops propelling himself and begins to coast across the ice, eventually coming to rest. The coefficient of kinetic friction between the ice and the skate blades is 0.100, and air resistance can be neglected.  How far will the skater travel before coming to rest?

Q13 answer both a and b....

A basketball player of mass m=88.4 kg jumps straight up for a ball. To do this, he lowers his body d1=0.44 m, then he accelerates through this distance by forcefully straightening his legs. This player leaves the floor with a speed sufficient to carry him d2=0.56 m above the floor. Write an expression for the speed v with which the basketball player leaves the floor. Write an expression for the speed v with wiich the basketball player leaves the floor. Write an expression for the acceleration, a, of the basketball player during the leg-straightening. Write an expression for the force upward force, FN, exerted on the basketball player by the floor during the leg straightening.  What is the magnitude, in newtons, of the force FN while the player is straightening his legs?
